CONTACTLESS CHARGING DEVICE

摘要

This contactless charging device reduces heat generation and can reduce a leakage magnetic field and superfluous radiation. The contactless charging device is used in charging using electromagnetic force, and has: a coil (311a) that generates electromagnetic waves; a shield section (310) that shields the electromagnetic waves; and a subcoil (331) that is disposed on the inside of the shield section (310) and recovers electromagnetic waves as electrical energy. The coil (311a) is a solenoid coil. Also, the subcoil (331) is disposed in the vicinity of two surfaces (A, B) on the central axis (X) of a wound wire of the solenoid coil among the four surfaces (A, B, C, D) that encircle the solenoid coil.
