A contactless charging system includes an electronic device and a charging device which includes an electricity transmission wire. The wire is disposed within a predetermined plane in a predetermined pattern by which directions of magnetic fields respectively generated in a first region and a second region into which an area where a ring-shaped frame of a case of the electronic device is disposed is divided are opposite to each other. The charging device applies an alternating current voltage having a predetermined frequency to the wire so as to generate the magnetic fields which change at the frequency, and charges an electricity accumulation unit of the electronic device disposed on the plane of the charging device by electromagnetic induction between an electricity reception coil of the electronic device and the wire.
A contactless charging system comprising:
A charging device which charges an electronic device in a contactless manner, the electronic device including a case including a ring-shaped frame, an electricity reception coil disposed in the case and an electricity accumulation unit connected to the electricity reception coil, the charging device comprising:
