A power-supply-side coil receives an alternating current from an AC power source to produce a magnetic flux. A power-supply-side capacitor is connected in parallel with the power-supply-side coil. A power-supply-side filter circuit includes a reactor and a capacitor, which are connected in series between the AC power source and the power-supply-side coil. A power-receiving-side coil is interlinked with a magnetic flux produced by the power-supply-side coil to produce an alternating current. The power-supply-side filter circuit, the power-supply-side capacitor, and the power-supply-side form a circuit having an impedance having a frequency characteristic, in which a frequency of a minimum point formed on a high-frequency side relative to a maximum point is greater than a frequency of a fundamental wave of an alternating current supplied from the AC power source and is less than a frequency of a third order wave of the fundamental wave. |
