<P>PROBLEM TO BE SOLVED: To provide an antenna structure which is excellent in radio wave reception performance and is not constrained in terms of materials and in terms of design, and a radio wave correction clock using the antenna structure. <P>SOLUTION: The antenna structure can receive external radio waves, and the antenna structure has a structure of a magnetic path in which a magnetic flux by the external radio waves can be received but the magnetic flux generated by resonance does not easily leak out of the antenna structure. The magnetic path comprises an antenna part constituted of at least one antenna core part and a coil part where a conductor is wound around the antenna core part to form a coil, and a cover part arranged near the antenna part covering at least a part of the antenna part. For the cover parts, at both end parts of the antenna core part of the antenna part, at least one of them is held and fixed so as to be separated from the antenna core part. <P>COPYRIGHT: (C)2007,JPO&INPIT |
