Provided is a contactless power supply system including a transmission-side resonance circuit configured to transmit electric power, a reception-side resonance circuit configured to receive the electric power from the transmission-side resonance circuit, an alternating current magnetic field generation circuit configured to generate an alternating current magnetic field for detecting a relative positional relationship between the transmission-side resonance circuit and the reception-side resonance circuit, and a magnetic field detector configured to detect the alternating current magnetic field. The contactless power supply system performs contactless electric power transmission of magnetic field resonance coupling between a ground-side device and a mobile body. A frequency of the position detecting alternating current magnetic field is different from a resonance frequency of each of the transmission-side resonance circuit and the reception-side resonance circuit.
