ELECTRONIC TIMEPIECE
First Claim
1. An electronic timepiece comprising:
- an optically transmissive dial having one surface to which external light is incident, and another surface from which the external light is emitted;
a solar battery disposed relative to the dial in the direction in which the external light is emitted, and having a photovoltaic solar cell;
an antenna disposed relative to the dial in the direction in which the external light is emitted, and configured to receive radio signals; and
a cover member having a first part disposed between the dial and the antenna;
the antenna having a part that does not overlap the solar cell in plan view from the thickness direction, which is perpendicular to the face of the dial; and
the first part having an overlap with the antenna in plan view, and in section view perpendicular to the thickness direction, having an overlap between the area where the first part is disposed in the thickness direction, and the area where the solar battery is disposed in the thickness direction.

Abstract
Provided is technology that suppresses increasing the thickness of the electronic timepiece when a member is provided to obscure the area where the solar battery is not located above the antenna. An electronic timepiece has: an optically transmissive dial; a solar battery having a photovoltaic solar cell; an antenna disposed relative to the dial in the direction in which the external light is emitted, and configured to receive radio signals; and a cover member having a first part disposed between the dial and the antenna. In plan view, the antenna has a part that does not overlap the solar cell; the first part has a part that does overlaps the part of the antenna that does not overlap the solar cell; and in section view perpendicular, has an overlap between the first part and the solar battery.
