Abstract
The present disclosure provides a non-contact charging apparatus including a power transmitting coil and a power receiving coil which face each other. At least one of the power transmitting coil or the power receiving coil includes a magnetic body and a coil wound around the magnetic body. The magnetic body has, on both end portions, exposed regions in which the wound coil is absent. One of the exposed regions that is on a face facing the power transmitting coil or the power receiving coil is larger than another one of the exposed regions that is on a face not facing the power transmitting coil or the power receiving coil.
