Non-contact Charging Module and Non-contact Charging Instrument

摘要

A noncontact charging module and a noncontact charger capable of reducing the thickness of the noncontact charging module while ensuring a sufficient cross-sectional area of the flat coil portion to improve power transmission efficiency. The non-contact charging module includes a flat coil part (2) having a plurality of conductive wires wound in a spiral shape and a magnetic sheet provided so as to face the coil (21) of the flat coil part (2) And the flat coil part 2 is partially wound in a plurality of stages and wound in a single stage.
