ABSTRACT:
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 includes a columnar magnetic core formed 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 suitable for installation on a wrist-watch type radio controlled timepiece, particularly requiring a reduction in size and weight. By this arrangement, while the time display dial is more easily viewable, the radio controlled timepiece ensures that a sufficient standard-wave receiving level is provided.
