WIRELESS CHARGING MODULE HAVING A WIRELESS CHARGING COIL AND A MAGNETIC SHEET

摘要

Provided are a non-contact charging module and a non-contact charging instrument such that the non-contact module can be made thin in a state where a sufficient cross-sectional area of a planar coil portion has been ensured and power transmission efficiency has been enhanced. The non-contact module comprises the planar coil portion (2) on which a plurality of conducting wires have been spirally wound, and a magnetic sheet provided so as to oppose a surface of a coil (21) of the planar coil portion (2), the plurality of conducting wires are respectively connected together at both ends, and the planar coil portion (2) has a part wound overlapped in multiple layers and another part wound in a single layer.
