Provided is a coil position detection method for a non-contact power supply system, configured to supply power from a power transmission coil on a ground side to a power reception coil on a vehicle side, by which a position of the power reception coil is detected. Output terminals of a rectifier circuit configured to rectify AC power received by the power reception coil are connected to a drive circuit and a battery. Moreover, a relay switch is provided between the battery and one of the output terminals of the rectifier circuit. When the relay switch is on, the coil position is detected based on AC voltage detected by a first voltmeter provided upstream of the rectifier circuit and, when the relay switch is off, the coil position is detected based on DC voltage detected by a second voltmeter provided downstream of the rectifier circuit.
