<P>PROBLEM TO BE SOLVED: To provide a radio-controlled timepiece with a solar battery, which receives an ultrahigh frequency while having the less decrease in reception performance of a planar antenna and having a conductor film pattern low in manufacturing costs. <P>SOLUTION: A radio-controlled timepiece with a solar battery includes: a planar antenna having a reception surface; and a solar cell substrate 11 which is provided on the side of the reception surface of the planar antenna and which has solar cells 11a and a floating conductor film 11b which is a conductor film electrically floating in at least a part of an area composed of a space 13a directly above the reception surface and its periphery 13b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
