发明名称 ANTENNA AND RADIO RECEIVER HAVING THE ANTENNA
摘要 An antenna that can ensure a sufficient radio receiving level and a radio-wave receiving device on which the antenna is equipped are provided. The antenna of the present invention is constituted by a columnar magnetic core formd by a ferromagnetic body, a coil portion wound around the magnetic core, a flat-plate state extension portion extended from an end portion of the magnetic core, and a standing portion provided at least on a one-direction face of the extension portion. Such antenna is equipped on a wrist-watch type radio controlled timepiece particularly requiring the reduction in size and weight. By this arrangement, while the time display measure is made easier to be seen, the radio controlled timepiece that can ensure the sufficient standard-wave receiving level can be provided.
