The first glass plate 11 and the second glass plate 12 are formed into a plate shape by, for example, a float method, and are bent and molded at a high temperature by gravity molding, press molding, or the like. The first glass plate 11 and the second glass plate 12 may be either untempered glass or tempered glass. The tempered glass may be either heat tempered glass or chemically tempered glass.

The interlayer film 13 joins the first glass plate 11 and the second glass plate 12. The interlayer film 13 may be a resin applied to laminated glass, for example, polyvinyl butyral resin (PVB), ethylene-vinyl acetate copolymer resin (EVA), or the like. The interlayer film 13 may have either a single-layer structure or a multi-layer structure. The number of glasses constituting the laminated glass 10 is not limited to two, and may be three or more. Since the interlayer film 13 joins three or more pieces of glass, two or more pieces may be used.

The first glass plate 11 may be arranged inside the vehicle more than the second glass plate 12. In that case, since the conductor 14 is formed on the surface of the first glass plate 11 facing the second glass plate 12, it has a function as a defogger for removing fogging of the window glass due to dew condensation. In this case, since the first glass plate 11 is located inside the vehicle, dew condensation adhering to the surface of the first glass plate 11 inside the vehicle can be efficiently removed.

The conductor 14 is fired after, for example, a conductive silver paste (a material having a resistivity of 0.5 to 9.0 × ^10-8 Ω · m) is printed / applied on the surface of the first glass plate 11. Is formed by When the conductor 14 is the above-mentioned bus bar, it may be a copper foil.

The metal film is formed by vapor deposition, sputtering, firing of a conductive paste such as a metal paste, or the like. The metal film may be processed into a desired pattern after film formation, or may be formed into a desired pattern during film formation. A photolithography method, an etching method, or the like is used for the former pattern processing, and masking tape or screen printing is applied for the latter pattern formation.

The insulator 25 is made of an insulating material, for example, a resin. The resin is preferably a material having excellent flexibility. The resin is not particularly limited, but for example, polyethylene terephthalate, polypropylene, polyethylene, polyimide, or the like is used.

The insulator 25 holds the first strip-shaped conductor 21 and the second strip-shaped conductor 22. As a result, the shapes of the first strip-shaped conductor 21 and the second strip-shaped conductor 22 can be maintained, damage to the first strip-shaped conductor 21 and the second strip-shaped conductor 22 can be suppressed, and handling such as transportation and storage can be performed. You can do it easily.

Further, the foil-shaped connecting member 20 is provided with a hollow portion 26 between the first strip-shaped conductor 21 and the second strip-shaped conductor 22 so that the first strip-shaped conductor 21 and the second strip-shaped conductor 22 are not exposed. ing.

Oxygen and moisture in the air do not enter between the connecting member 20 and the second glass plate 12, and they are firmly adhered by the interlayer film 13.

Then, in the foil-shaped connecting member 20, the conductor 14 is formed in the vicinity of the portion where the first strip-shaped conductor 21 and the second strip-shaped conductor 22 are provided and the end portion of the first glass plate 11. An adhesive member 30 is provided between the portion and the portion not provided. Therefore, oxygen and moisture in the air do not enter between the foil-shaped connecting member 20 and the first glass plate 11, and the foil-shaped connecting member 20 and the first glass plate 11 are firmly adhered to each other. To.

The adhesive member 30 may be a double-sided tape or an adhesive, but if it is a double-sided tape, the adhesive does not flow to the hollowed portion 26 and no time is required for the adhesive to solidify, which is preferable. .. The double-sided tape may be a known one. The adhesive is not particularly limited, but an acrylic resin-based adhesive, a urethane resin-based adhesive, an epoxy resin-based adhesive, or the like can be used.

Therefore, in the vehicle window glass 100, the foil-shaped connecting member 20 pulled out from between the first glass plate 11 and the second glass plate 12 of the laminated glass 10 enters the adhesive member 30 and the hollowed out portion 26. However, due to the adhesive effect of the interlayer film 13, the foil-like connecting member 20 is bonded more firmly. Even if it is pulled to the outside of the laminated glass 10, the foil-like connecting member 20 is firmly joined without coming out of the laminated glass 10.

As shown in FIGS. 2 and 3, one end of the foil-shaped connecting member 20 is located between the first glass plate 11 and the second glass plate 12. A terminal portion 23 not covered with the insulator 25 is provided at a portion of the foil-shaped connecting member 20 located between the first glass plate 11 and the second glass plate 12, and the terminal portion 23 is provided. , The conductor 14 formed on the surface of the first glass plate 11 facing the second glass plate 12 is electrically connected by the solder 40.

The melting point of the solder 40 is preferably lower than the temperature heated in the step of laminating the first glass plate 11, the second glass plate 12, and the interlayer film to obtain the laminated glass 10.

In the step of obtaining the laminated glass 10, the first glass plate 11, the interlayer film 13, and the second glass plate 12 are stacked in this order and then heated and pressurized. The heating temperature is preferably 120 to 150 ° C., and the pressurized pressure is preferably 1.03 × 10 ^{6 to} 1.27 × 10 ⁶ Pa / m ² .

When the melting point of the solder 40 is higher than the above-mentioned heating temperature, the first glass plate 11 on which the conductor 14 is formed must be locally heated to melt the solder 40. Normally, the conductor 14 is often formed in the vicinity of the short side of the glass. Therefore, if the vicinity of the short side of the glass is locally heated, the glass may be broken due to thermal stress. Further, in the vehicle window glass of the present invention, the portion of the conductor 14 formed on the surface of the first glass plate 11 that is electrically connected to the connecting portion 23 is not exposed in the laminated glass 10. Therefore, it cannot be connected after the step of making the laminated glass 10.
