When a distance between coils is detected, a measuring device measures a power reception voltage VR. A notifying device notifies the distance between the coils based on a measurement result by the measuring device. A power reception unit is configured such that a characteristic of power reception voltage VR with respect to the distance between the coils has a plurality of extreme values in accordance with change in the distance between the coils. When a local minimum value of power reception voltage VR is detected during execution of alignment, a vehicle ECU controls the notifying device to notify the distance between the coils corresponding to the detected local minimum value of power reception voltage VR, by using the characteristic of power reception voltage VR prepared preliminarily.
