Abstract
Provided is a non-contact charging module wherein adverse effects from magnets have been prevented even where magnets are used for positioning, power transmission efficiency has been improved, and the entire module has been made thin due to a state of improved power transmission efficiency. The non-contact charging module comprises a planar coil portion (2) of spirally wound conductive wiring, and a magnetic sheet (3) that is provided so as to oppose a surface of a coil (21) on the planar coil portion (2), and is characterized in that the magnetic sheet is layered with a first layer, and a second layer that has a lower magnetic permeability and a higher saturation magnetic flux density than the first layer.
