CONTACTLESS CHARGING MODULE, CONTACTLESS CHARGING DEVICE, AND METHOD OF MANUFACTURING CONTACTLESS CHARGING MODULE

Document Type and Number:

WIPO Patent Application WO/2012/120896

Kind Code:

A1

Abstract:

Provided is a contactless charging module, a contactless charging device, and a method of manufacturing the contactless charging module, wherein a magnetic sheet can be prevented from being damaged and giving an adverse effect on power transmission characteristic, by adopting a flexible magnetic sheet having slits, and wherein power transmission efficiency of the contactless charging module can be prevented from decreasing significantly. The contactless charging module is provided with: a planar coil unit; a magnetic sheet upon which the planar coil unit is to be mounted; a recess section or a slit that is formed on the magnetic sheet, and that is for housing therein a portion of a conductor wire of the planar coil unit; and a plurality of flexible slits that are for giving flexibility to the magnetic sheet. At least one of the plurality of flexible slits is formed such that a virtual extension line of the flexible slit will be arranged within the width of the recess section or the slit.
