加工精度が悪い場合も上述と同様である。In a conventional watch coil, for example, the coil lead board 2
Even if the coil lead pattern 3 is processed with high accuracy, if the pattern processing accuracy of pattern 3 for coil lead is poor, the basic magnetic core l
The position of the coil lead pattern 3 may be misaligned with respect to the hole 6 at the end of the coil lead pattern 3, which may result in poor electrical contact with the circuit board pattern and an electrical short between the short-circuit set screw and the coil lead pattern 3. Further, even if the coil lead pattern 3 is processed with high accuracy, the same situation as described above occurs when the coil lead board 2 is processed with poor accuracy.

FIGS. 1(4) and 1D are a partial plan view and a side sectional view of a watch coil according to an embodiment of the present invention. In the figure, the entire magnetic core 1 of the watch coil is coated with an insulating coating 5 by vacuum-depositing thermoplastic resin, and a coil lead pattern 3 is further provided on the top surface by electroless nickel plating. .
