Patent ID: 8547058

Claim:
A reception-side non-contact charging module that receives power from a transmission-side non-contact charging module by an electromagnetic induction and that has a case where a magnet included in the transmission-side non-contact charging module is used to align with the transmission-side non-contact charging module or a case where the magnet is not used to align with the transmission-side non-contact charging module, the reception-side contact charging module comprising: a planar coil portion in which a conducting wire is wound; and a magnetic sheet that places a coil surface of the planar coil portion and faces the coil surface of the planar coil portion, wherein the magnetic sheet has a concavity of a predetermined depth provided within an inner winding of the planar coil portion, and wherein the predetermined depth of the concavity is 40 to 60% of a thickness of the magnetic sheet.
