A power reception coil of a power reception unit is configured to receive, in a contactless manner, the electric power output from a power transmission coil of a power transmission unit. A rectifying circuit includes a rectifier and a capacitor provided on an output side of the rectifier, and rectifies the electric power received by the power reception coil. A voltage sensor is provided on an output side of the rectifying circuit. A vehicle ECU detects rising of a voltage detected by the voltage sensor, and detects a distance between the coils based on a movement distance of a vehicle from a reference distance indicative of the distance between the coils at which the rising of voltage occurs, the reference distance is prepared in advance.
