PROBLEM TO BE SOLVED: To suppress variation in inductance of a feeder line for supplying power in non-contact manner. SOLUTION: A resonant capacitor 111 is connected to a feeder line 110, constituting a resonance circuit together with the feeder line 110. A feeder line pseudo unit 120 is connected in parallel to the feeder line 110. A power source 300 outputs an AC current of specified frequency to the feeder line 110 by an inverter circuit. The switching frequency of the power source 300 is so adjusted as to agree with the resonance frequency of a circuit consisting of the feeder line pseudo unit 120 and resonant capacitor 111 as well as the feeder line 110. An inductive reactance component ln occurs at the feeder line 110 when a mobile body receives power supply from the feeder line 110, however, since a reactor Lp and resistor Rp are connected in parallel to the ln, the effect of ln is suppressed.
