PROBLEM TO BE SOLVED: To provide a wire used for a detector element that performs the detection or rectification even in a high frequency range, and stably operates even at high temperature. SOLUTION: The wire consists of a ferromagnetic material having conductivity, and has a thickness being not more than ten times as large as skin depth in accordance with high frequency power to be supplied. When the wire is supplied with a predetermined high frequency power while the magnetic moment in the wire is not uniform, a DC voltage is outputted when the frequency of the high frequency power corresponds to a predetermined resonance frequency. At that time, since impedance of the wire is also changed, the ferromagnetic wire is further used for a transmission channel or a transmission filter. The wire is not limitedly used for a detector element, and directly used as a tag of RFID, a transmission channel, a transmission filter, a magnetic field sensor and the like. Moreover, since the wire has an extremely simple structure, it is low in manufacturing cost, and stable in operation. COPYRIGHT: (C)2007,JPO&INPIT
