Abstract:
1. An electronic timepiece having a radio communication function, comprising: a case member, and a back cover integrated with, or attached to, the case member, the case member and the back cover made of metal or alloy, the case member with which the back cover has been integrated or to which the back cover has been attached defining an interior and having an open end; an antenna housed in the interior; a support substrate made of a nonconductive and nonmagnetic material, the support substrate having a first face that faces toward the open end and a second face that faces toward the back cover; a photoelectric generator disposed in the interior, the photoelectric generator having a photoelectric conversion element that is supported on the first face of the support substrate and that faces outwardly toward the open end to receive light, the photoelectric conversion element being configured to generate electricity from the received light; a time display unit configured to display the time; and a drive unit configured to drive the time display unit using electricity generated by the photoelectric generator; wherein the antenna is disposed on the second face of the support substrate or proximally to the second face between the second face and the back cover, with an axis of the antenna being substantially parallel to the plane of the second face of the support substrate, such that the antenna is in a position overlapping the support substrate as seen in a plan view of the electronic timepiece.
