Abstract
The present invention relates to a timepiece and an electronic apparatus, which comprise a casing, a digital face and a time counting module, both being provided in the casing. A bulb-shaped solar battery element is mounted on the digital face. The bulb-shaped solar battery element is allowed to receive the external light sufficiently to generate the electric power efficiently.
