<P>PROBLEM TO BE SOLVED: To provide a wireless power transmission coil with which a coil of high inductance can be obtained without incurring insulation breakdown by extending a transmission distance, achieving high transmission efficiency and reducing influences of displacement. <P>SOLUTION: The present invention relates to a wireless power transmission coil formed by winding a twisted wire conductor, in which a plurality of short-circuiting elements are provided in the middle of the twisted wire conductor. The plurality of short-circuiting elements are provided in such a way that a voltage generated between the short-circuiting elements becomes lower than an insulation breakdown voltage of the twisted wire conductor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
