Title:
非接触充電モジュール及びこれを備えた送信側非接触充電機器と受信側非接触充電機器
Document Type and Number:
Japanese Patent JP4900525
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact charging module and a non-contact charging apparatus in which power transmission efficiency can be enhanced by providing a magnetic sheet that is less susceptible to the adverse effects due to an alignment magnet and can be made thin, thereby preventing the adverse effects from the magnet even if the alignment magnet is used, and to provide the non-contact charging module and the non-contact charging apparatus in which the entire module is made thin while enhancing power transmission efficiency.SOLUTION: The non-contact charging module comprises a planar coil 2 formed by winding a conductor, and a magnetic sheet 3 provided to face the surface of a coil 21 in the planar coil 2. The magnetic sheet 3 is an MnZn-based ferrite sheet having a permeability of 250 or higher, a saturation magnetic flux density of 350 mT or higher, and a thickness of 400 μm or more.
