<P>PROBLEM TO BE SOLVED: To provide a non-contact power feeding system reducing a loss due to a Joule's heat generated in a feeder and being capable of improving a power efficiency. Ž<P>SOLUTION: The non-contact power feeding system consists of a carrier car 1 and a feed facility 3 capable of supplying the carrier car 1 with a power in a non-contact. The carrier car 1 includes: a digital voltmeter 27 detecting an output voltage Vp from a rectifying circuit 13; and an optical transmitter 23 transmitting an output signal from the digital voltmeter 27 to a high-frequency power supply 7. The feed facility 3 includes a control circuit 9b controlling an induced current output from the high-frequency power supply 7 so that the output voltage Vp approaches to a target value Vmin' while the output voltage Vp is kept at the preset target value Vmin' or more by a transmission from the optical transmitter 23.
