Abstract
An electronic timepiece that uses electrical power produced by photovoltaic generation as a power source and has a function for receiving microwave signals, including a dial for displaying time information on a front surface thereof, a solar cell that receives light passing through the dial and produces electrical power by photovoltaic generation, and an antenna that is disposed so that at least part of the signal receiving surface opposes at least a part of the back surface of the dial, and receives microwave signals through the dial. The solar cell is not disposed in space between the back side of the dial and the signal receiving surface of the antenna.
