Abstract:
An electronic timepiece includes a tubular exterior case, a cover glass plate that blocks one of two openings of the exterior case, a ring-shaped antenna body provided along an inner circumference of the exterior case, a circuit substrate which is provided in a position below the antenna body when viewed from the cover glass plate and on which a shield pattern G is formed, and a GPS receiver that is so provided on the circuit substrate that the GPS receiver faces away from the antenna body with the shield pattern G being a boundary and amplifies and processes a signal received by the antenna body.
