<p>PROBLEM TO BE SOLVED: To provide a structure of a solar cell which is used in an atomic clock receiving high frequency wave and does not deteriorate reception performance.SOLUTION: An electrode of a solar cell, which may affect reception performance, is not planarly overlapped with an antenna. Specifically, in an area outside an area covered by projection of the antenna, a solar-electrode-no-arrangement area is provided in which no metal element is arranged but only a nonconductive member is arranged. In addition, a solar colored part in which the solar-electrode-no-arrangement area is colored may be provided.</p> |
