ABSTRACT:
An electronic timepiece with an internal antenna has an antenna that has an elongated magnetic core formed from a magnetic body and a coil wound around the magnetic core, and can receive external wireless information, the magnetic core having a coil winding part to which the coil is wound in the lengthwise center part of the magnetic core, and a pair of lead parts extending from both ends of the coil winding part; a module that houses the antenna and processes the external wireless information; and a magnetic member that is positioned with a predetermined gap between the magnetic member and the lead part at a position that is not superposed on a coil-overlapping area that overlaps the coil winding part of the antenna and is superposed on at least a part of a lead-overlapping area that overlaps the pair of lead parts when the electronic timepiece with internal antenna is viewed in plan view from the timepiece thickness direction of the electronic timepiece with internal antenna.
