Filters, resonators, or similar devices that process signals. Description of the Related Art In Fig. 5, a specific structure of an example of a conventional inductor of this type is shown. The inductor 50 includes an insulating plate 51 having spiral coil wire patterns 5 3 and 5 4 on its respective surface, and an insulating plate 51 having lead patterns 5 2 and 5 5 on its respective surface, and on its surface. The insulating cover plate 51 of the lead pattern is not manufactured in advance. The coil wire patterns 5 3 and 5 4 are electrically connected in series through the through holes 5 7 b provided in the insulating plate 51 to form a line 圏 L. In the coil wire patterns 5 3 and 5 4, respective end points are electrically connected to the lead patterns 5 2 and 5 5 through respective through holes 5 7 a and 5 7 c provided in the insulating plate 51. After being sequentially placed, the insulating plate 51 is fired into a laminated body. On the surface of the laminated body, external input / output electrodes electrically connected to the lead patterns 5 2 and 55 are formed. In the conventional inductor 50, each of the spiral wire coil wire patterns 53 and 54 has a fixed width and thickness at any position. In addition, since each of the coil wire patterns 5 3 and 5 4 has a spiral shape, the straight line length of one turn of the coil is longer at the outer portion of the coil than at the inner portion thereof. Because 3 < please read the phonetic items on the back before filling out this page) Loading --- I l ·-丨 Order · -------- This paper size applies to China National Standard (CNS) A4 specifications ( 210 X 297 mm) A7 4 6 3 i __B7_____ V. Description of the invention) Therefore, in the coil wire pattern 5 3 and 5 4 respectively, the direct current (DC) resistance of the straight line located on the outer part of the spiral is relatively low. The straight line in its inner part is large. This result increases the DC resistance 値 of the entire coil wire pattern 5 3 and 54. Here, it is assumed that the inductance 値 is L, the DC resistance 値 is R, and the resonance frequency is f. Then, Q 値 is expressed as Q = 2 π f 〇L / R ° Since the conventional inductor 50 has a large DC resistance as described above, the conventional inductor 50 has a problem of low Q 値. . SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an inductor 'which has a low DC resistance 値 and a high Q 値. In order to achieve the above object, the inductor of the present invention includes an insulating member and a spiral wire coil wire pattern formed on a surface of the insulating member, wherein a width of the coil wire pattern is at a middle portion and an outer side of the spiral. The part is larger than its inner part. Since the width of the coil wire pattern is larger than the inner part of the spiral in the middle and outer parts, the cross-sectional area of the coil wire pattern is larger than the inner part of the spiral in the middle and outer parts. Therefore, the DC resistivity (DC resistance 外侧 per unit length) of the middle and outer portions of the spiral is smaller than the inner portion of the spiral. This reduces the DC resistance of the entire coil wire pattern. In addition, if the coil wire pattern has three turns, and the pattern width of the middle part of the spiral is greater than the pattern width of the inner and outer parts, the coil wire pattern The cross-sectional area of the paper is on the inside, outside and middle of the spiral. 4 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page). -" l · ——— Order --------- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 63 1 35 a?

The inductor 1 includes an insulating plate 11 ′ having three spiral coil wire patterns 3 and 4 formed on its respective surfaces, and an insulating plate 11 having lead patterns 2 and 5 formed on its respective surfaces, and on its surface. No insulating cover plate 1 1 of the coil pattern is manufactured in advance. The insulating board 1 1 is kneaded into the board from a dielectric powder or a magnetic powder with a binder and 6 paper sizes are applicable to China National Standard (CNS) A4 (210 X 297 mm) 4 63 1 A7 B7 V. Invention ≪). The patterns 2 to 5 are composed of silver, palladium, copper, nickel, gold, silver-palladium alloy, or similar metals. The patterns 2 to 5 are made by, for example, a method combining a lithography technique and a wet etching technique. Specifically, a wire layer composed of silver and the like is provided on the entire surface of the insulating plate 11 using, for example, printing, sputtering or deposition techniques. A photoresist layer is formed on this wiring layer. Then, the photoresist layer is covered with a photomask and then exposed. Next, the exposed photoresist layer is subjected to a development process, and unnecessary portions of the photoresist layer are removed. Next, the wiring layer is removed with an etchant, leaving a portion covered with a photoresist layer. Thereby, patterns 2 to 5 with high accuracy can be formed. By this, the remaining photoresist layer is removed. In the coil wire patterns 3 and 4, one of the respective end points 3 a and 4 a is placed on the peripheral edge portion of the outer side of the insulating plate 1 1, and the other end points 3 b and 4 b are both It is placed on the middle part of the insulation board 11, and the spiral part is extended between the outer peripheral edge part and the middle part of the spiral. The coil wire patterns 3 and 4 are each arranged such that the pattern width of the middle portion j and the outer portion k of the spiral is larger than the inner portion i of the spiral. In the case of the embodiment of the present invention, the width of each of the coil wire patterns 3 and 4 increases in increasing order in the inner portion i, the middle portion j, and the outer portion k of the spiral. The coil wire patterns 3 and 4 are electrically connected in series with each other through a through hole 7 b provided in the insulating plate 11 and define a coil L. One end of the lead-out pattern 2 is exposed on the left side of the insulating plate 11. One end of the lead-out pattern 5 is exposed on the right side of the insulating plate 11. The lead-out patterns 2 and 5 respectively pass through 7 paper sheets set on the insulating board 11. The paper size is applicable to China National Standard (CNS) A4 specifications (2) 0 X 297 mm> (Please read the precautions on the back before filling in this Page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6 A7 B7 V. Description of the Invention (b) Through holes 7 a and 7 c are electrically connected to the line conductor patterns 3 and 4 respectively. After sequential stacking and pressure bonding, the above magnetic plate 11 is fired into a laminated body 15 as shown in Fig. 2. The end portions of the left and right ends of the laminated body 15 are respectively The input external electrode 2 1 and the output external electrode 2 2 are formed by a coating technology, a transfer technology, a sputtering technology, or the like. The materials of the external electrodes 21 and 22 are silver, silver-palladium alloy, nickel, and copper. Or similar metal. The input external electrode 21 is electrically connected to one end of the coil L through the lead-out pattern 2, and the output external electrode 2 2 is electrically connected to the coil L through the lead-out pattern 5. The other end. In the single-element inductor 1 described above, The width of cases 3 and 4 in the middle part j and the outer part k of the spiral is larger than the inner part i, so the cross-sectional area of each coil pattern 3 and 4 is in the middle part j and the outer part k is larger than the inner portion i. Therefore, the DC resistivity of the middle portion j and the outer portion k of the spiral is smaller than the inner portion i of the spiral. This makes the DC resistivity of the entire coil wire pattern 3 and 4 Is lower than the conventional coil wire pattern with a fixed width. This makes the inductor 1 have a high Q 値. In addition, by keeping the width W (refer to FIG. 4) of the inner part to the outer part of the wire lead pattern, and The conventional width is the same, and the above-mentioned effect can be obtained without reducing the inductance. [Second Embodiment] In FIG. 3, the inductor of the second embodiment of the present invention is shown.

Invention Description (< j ) Specific structure. Inductor 2 0 uses insulating plates 2 1 and 21, each of which has a circular coil wire pattern 2 3 and 2 4 formed on the surface thereof, instead of the inductor 1 used in the first embodiment, which are respectively used on its face. Insulating plates 1 1 and 1 1 forming square coil wire patterns 2 3 and 2 4. Each of the coil wire patterns 23 and 24 has three turns, and the pattern width increases in an increasing order in the inner portion i, the outer portion k, and the middle portion j of the spiral. Therefore, the cross-sectional areas of each of the coil wire patterns 23 and 24 are increased in an increasing order in the inner portion i, the outer portion k, and the middle portion j of the spiral. Therefore, the DC resistivity of each of the coil wire patterns 2 3 and 24 decreases in decreasing order in the inner portion i, the outer portion k, and the middle portion j of the spiral. This reduces the DC resistivity of the entire line and lead patterns 23 and 24. Here, in order to avoid repeated explanation, similar parts are marked with the same reference numerals in FIGS. 1 and 3. [Other Embodiments] The present invention is not limited to the above embodiments, and various structures can be adopted within the scope of the actual spirit of the present invention.

Description of the invention (required) Form the desired wire pattern. Next, apply a paste-like insulating material on the wire pattern, and thereby form an insulation layer with a built-in wire pattern. In the same way, by continuously By repeating this alternately overlapping insulating layer and wire layer, an inductor having a single structure can be obtained. In addition, the inductor of the present invention is not limited to a laminated type, but may be any type of ceramic or Inductors with spiral wire conductor patterns on the surface of an insulating substrate made of similar materials. Similarly, the number of turns of the spiral wire conductor patterns is not specifically three, but may be two or more. In the following, there will be explained The structure shown in Figure 3 Example of the transformer 2 0. The DC resistance of the inductor 20 is obtained by setting Re (the radius (thickness: 0.0 1 5 mm) of the coil wire patterns 2 3 and 24) to 1.9 mm and W (from the outside The width of the part k to the inner part i) is set to 1 mm, and d (the distance between the inner part i, the middle part j, and the outer part k of the spiral) is set to 0.1 mm, and by the preparation ratio . 値 i: j: k (the ratio 图案 of the pattern width of the inner portion i, the middle portion j, and the outer portion k) are measured as shown in the following Table 1 and Table 2 with greatly changed samples.

In addition, when the pattern width increases in the increasing order of the inner part i, the outer part k, and the middle part j of the spiral, it is compared with a conventional sample having a ratio 値 i: j: k = 1: 1: 1 In comparison, its DC resistance 値 is also reduced. It can be understood from the above explanation that, as in the present invention, because the coil wire pattern is configured such that the pattern width of the middle and outer portions of the spiral is greater than the width of the inner portion of the spiral, the cross-sectional area of the coil wire pattern is between The middle and outer parts of the spiral are larger than the inner parts.
