<P>PROBLEM TO BE SOLVED: To provide a small-sized electronic timepiece with a built-in antenna capable of maintaining the receiving performance of a GPS at a sufficiently high level while achieving miniaturization of an antenna. <P>SOLUTION: An electronic timepiece with a built-in antenna includes: a cylindrical outer case 80 of which at least a part is formed of a nonconductive member; a time display part which displays time inside the outer case 80; an antenna body 40 which is housed in the outer case and has a shape formed by notching a part of a circular shape; and a pair of power feeding electrodes 40a and 40b which sandwich a recessed portion of the antenna body 40 and feed electric power to the antenna body 40. The antenna body 40 is disposed along the outer edge of a dial plate 11, and the power feeding electrodes 40a and 40b are disposed in a range of 06:00 to 10:00 of the time display part or in a range of 12:00 to 04:00 thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
