Abstract
A timepiece includes a dial plate, and a solar battery which is disposed on a rear side of the dial plate. The dial plate is provided with grooves or ridges. The grooves or the ridges have portions where inclination angles with regard to a normal line of the dial plate are different, and due to this, light which is transmitted through the dial plate is incident from a plurality of directions with angles which are different with regard to the solar battery.
