ABSTRACT:
A wave timepiece has an antenna disposed within or on the side of a case. The antenna has a magnetic core member comprised of magnetic foils that are superposed and stacked one over the other in the radial or transverse direction of the case and laminated together to form a laminated body, and a coil wound around the magnetic core member. Typically, the antenna is disposed in the case between a dial window and a rear cover, and the laminated body of magnetic foils is curved in conformity with the inner circumferential curved face of the case. The wave timepiece exhibits improved reception sensitivity due to the radial or transverse stacking of the magnetic foils.
