Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic timepiece with a solar battery including a film-type solar battery, and less susceptible to effect of static electricity.SOLUTION: An electronic timepiece with a solar battery includes: an exterior case formed of electroconductive material; a solar battery unit 4 accommodated in the exterior case; and a movement 2 that has a secondary battery for accumulating electric energy, housed in the exterior case. The solar battery unit 4 has: a solar battery 40 using a film-made base 41; a positive pole and a negative pole formed on a rear face of the base 41 of the solar battery 40; and an electroconductive solar battery guide plate 45 bonded to the rear face of the base 41 without contact with the positive pole and the negative pole. A positive pole of the solar battery 40 is conducted to a positive pole of the secondary battery, a negative pole of the solar battery 40 is conducted to a negative pole of the secondary battery, and the solar battery guide plate 45 is conducted to an electrode which is set as a ground electrode out of the positive pole and the negative pole of the secondary battery.SELECTED DRAWING: Figure 2
