## Abstract

An electric power reception device for a vehicle is equipped with an electric power reception unit that is configured to be able to receive electric power from an electric power transmission device in a non-contact manner, a communication portion that transmits information on a position or dimension of the electric power reception unit to the electric power transmission device, and a vehicle ECU that controls the communication portion. Preferably, the vehicle ECU transmits pre-stored information to the electric power transmission device with the aid of the communication portion, before allowing a vehicle to be parked at an electric power reception position of the electric power transmission device. The information includes at least one of a size of the electric power reception unit, a size of the vehicle in which the electric power reception unit is mounted, and a mounting position of the electric power reception unit in the vehicle.
