PROBLEM TO BE SOLVED: To provide a non-contact power supply system and a power receiver which guide a vehicle to a parking position where electric power can be supplied in high efficiency and perform electric power supply.SOLUTION: A non-contact power supply system comprises: a power transmission coil 9 for transmitting electric power, which is installed on the ground side; a power receiving coil 10 for receiving the electric power transmitted from the power transmission coil 9 in a non-contact state, which is mounted on a vehicle 21; a power storage device 4 to which the received electric power is supplied; and a power receiving voltage detection circuit 13 for detecting a received voltage. The non-contact power supply system transmits the electric power at a constant output, presents information for guiding the vehicle 21 to a position where the received voltage becomes the maximum value, and supplies the electric power to the power storage device 4 at the position. 【課題】高効率で給電が可能な駐車位置に車両を誘導し、給電を行う非接触給電システム及び受電装置を提供することを目的としている。【解決手段】地上側に設置されるとともに電力を送電する送電コイル９と、車両２１に搭載されるとともに送電コイル９から送電された電力を非接触により受電する受電コイル１０と、受電された電力が給電される蓄電装置４と、受電された電圧を検出する受電電圧検出回路１３と、を備え、電力を一定の出力で送出し、受電された電圧が最大値となる位置に車両２１を誘導する情報を提示し、当該位置において蓄電装置４に給電を行う。【選択図】図１
