<P>PROBLEM TO BE SOLVED: To provide an electronic timepiece with a built-in antenna, which allows a magnetic field-concentrating component to be arranged at a location having few restrictions on the arrangement position and the size. <P>SOLUTION: A radio wave correction timepiece 1 comprises an exterior case 20, a dial plate 14 which is arranged in the exterior case 20, a dial ring 25 which is arranged on the front side of the dial plate 14, an antenna 100 which is arranged on the rear side of the dial plate 14, and a magnetic field-concentrating component 61. The antenna 100 comprises an antenna core 110 formed of a longitudinal magnetic material and a coil 120 which winds around the antenna core 110. The magnetic field-concentrating component 61 is magnetically coupled with the antenna core 110 and arranged in the dial ring 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
