Abstract
An electronic timepiece that receives signals and displays information can be driven using solar power while suppressing antenna sensitivity loss to a sufficiently low level. An electronic timepiece has a dial, on the face of which time is displayed, a flat antenna, and a solar cell. The flat antenna is disposed in an area on the back side of the dial, extends in the plane direction of the dial, and receives signals passing through the dial. The solar cell is also disposed in the area on the back side of the dial, positioned vertically between the dial and the flat antenna. The solar cell also extends in the plane direction of the dial.
