<P>PROBLEM TO BE SOLVED: To provide a non-contact charging module which reduces its size while maintaining power transmission efficiency by reducing influences of a magnet field of a positioning magnet in a non-contact charging module having a planar coil part formed by a spiral electric wire part and a magnetic sheet, and to provide a non-contact charger using the non-contact charging module. <P>SOLUTION: When the shortest distance between facing inner sides of a planar coil part 2a, in which a coil is formed by winding a conductor wire into a substantially rectangular shape on a planar surface, is defined as y1, and the diameter of a magnet 4 used for positioning between a power transmission non-contact charging module and a power reception non-contact charging module is defined as m, the relationship y1≥m is satisfied. <P>COPYRIGHT: (C)2013,JPO&INPIT |
