<P>PROBLEM TO BE SOLVED: To provide a noncontact charging module, having a planar coil part composed of a spiral lead part and a magnetic sheet, and a noncontact charger, capable of reducing the thickness of the noncontact charging module while sufficiently ensuring a cross sectional area of the planar coil part. <P>SOLUTION: The noncontact charging module comprises; a planar coil part 2 with a lead spirally wound; and a magnetic sheet 3 disposed opposing to a surface of a coil 21. The magnetic sheet 3 is provided with a recess 33 or a slit, which is perpendicular to a tangential line of a circumference of an inner circle of the surface of the coil 21 and extends from either a winding start point or a winding end point of the surface of the coil 21 to an end of the magnetic sheet 3 in the shortest distance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
