Patent ID: 8552684

Claim:
A non-contact charging module that performs power transmission by an electromagnetic induction with another non-contact charging module that comprises a first hole and that is allowed to align with the other non-contact charging module in either a first case or a second case, the first case being a case where a magnet included within the first hole in the other non-contact charging module is used when alignment with the other non-contact charging module is performed, the second case being a case where the magnet is not within the first hole and thereby not used when the alignment is performed, the non-contact charging module comprising: a planar coil portion in which a conducting wire is wound in a substantially rectangular shape and that comprises a second hole of a predetermined size, the second hole being provided within an inner winding of the planar coil portion; and a magnetic sheet on which a coil surface of the planar coil portion is placed and that faces the coil surface of the planar coil portion, wherein a length of a shortest distance between opposed inner sides of a substantially rectangular hollow portion of the planar coil portion is longer than a diameter of the magnet, and the predetermined size of the second hole is greater than 15.5 mm.
