Zusammenfassung:	The present invention provides a non-contact charging system which can transmit the information on the reception state from an electric power receiving device to an electric power transmitting device while performing the electric power reception. The non-contact charging system is configured with an electric power transmitting device which performs electric power transmission at a resonance frequency and an electric power receiving device which performs electric power reception at the resonance frequency. The electric power receiving device includes an adjustment unit which can adjust the resonance frequency; and a receiving-side control unit for adjusting the resonance frequency when a prescribed condition is satisfied. The electric power transmitting device includes a reflected wave detection unit which detects a reflected wave from the electric power receiving device; an extraction unit which extracts reception information included in the reflected wave; and a transmitting-side control unit which controls the electric power transmission.
