NON-CONTACT CHARGING MODULE AND RECEPTION-SIDE AND TRANSMISSION-SIDE NON-CONTACT CHARGING APPARATUSES USING THE SAME
First Claim
1. A non-contact charging module that has a case where using a magnet included in a counterpart-side non-contact charging module or a case where not using the magnet, when aligning with the counterpart-side non-contact charging module, the non-contact charging module comprising:
- a planar coil portion where electrical lines are 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 a size of a hollow portion of the planar coil portion is more than a size of the magnet included in the counterpart-side non-contact charging module.

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.
