CONTACTLESS CHARGING MODULE AND RECEIVING-SIDE AND TRANSMISSION-SIDE CONTACTLESS CHARGER USING SAME

摘要

A contactless charging module which, during alignment with another contactless charging module, sometimes uses a magnet provided in the other contactless charging module and sometimes does not use the magnet, wherein said contactless charging module can be used without changing the L value of the coil provided therein. This contactless charging module is characterized by being provided with a planar coil unit which comprises a wound conducting wire, and a magnetic sheet on which the coil surface of the planar coil unit is placed and which is arranged so as to face the coil surface of the planar coil unit, and is further characterized in that the magnetic sheet is provided with a hole within the position corresponding to a hollow portion of the planar coil unit.
