Abstract:
It is an object to provide a non-contact charging module that prevents the magnet from negatively influencing particularly the inside portion of a coil and improves power transmission efficiency, even when a magnet is used for alignment. This non-contact charging module is a reception-side non-contact charging module, to which power is transmitted from a transmission-side non-contact charging module which is equipped with magnet, by electromagnetic induction, in which the non-contact charging module includes a planar coil portion around which spiral electric lines are wound, and a magnetic sheet disposed to face the surface of coil of the planar coil portion so that it faces the magnet of the transmission-side contact module, in which the inner diameter of the planar coil portion is larger than the magnet.
