<P>PROBLEM TO BE SOLVED: To provide a non contact charging module and a non contact charger which achieve the thickness reduction while ensuring the electrical insulation between a conducting wire and a magnetic sheet. <P>SOLUTION: A non contact charging module includes: a planar coil part around which a conducting wire is spirally wound; a Mn-Zn ferrite sheet 3 which allows the planar coil part to be placed thereon and is provided so as to face a coil surface of the planar coil part, which is the side placed on the Mn-Zn ferrite sheet 3, through an insulation sheet 4; and a recessed part 33 or a slit which is provided at the Mn-Zn ferrite sheet 3 and extends from a wind-start point of the coil surface to an end part of the magnetic sheet 3. The conducting wire of the planar coil part is housed in the recessed part 33 or the slit with the insulation sheet 4 pressed into the recessed part 33 or the slit, and the conducting wire of the planar coil part is insulated from the Mn-Zn ferrite sheet 3 by the insulation sheet 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
