<P>PROBLEM TO BE SOLVED: To provide a built-in antenna type electronic timepiece which can respond to miniaturization and excels in antenna reception sensitivity. <P>SOLUTION: A radio wave corrected timepiece has an antenna 21 which receives standard frequency broadcast, a receiving means which processes the received standard frequency broadcast, a module which holds the antenna 21 and the receiving means inside and an exterior case which holds the module inside. The antenna 21 has a magnetic core 211 constituted by stacking in lamination a plurality of amorphous foils 214 having longitudinal shapes and a coil 212 wound on the magnetic core 211, and the magnetic core 211 has a plurality of ordinary amorphous foils 214A and extended amorphous foils 214B having a larger size along the longitudinal direction than the ordinary amorphous foils 214A. <P>COPYRIGHT: (C)2010,JPO&INPIT |
