A vehicle (100) includes a power reception unit (110) for receiving electric power for running of the vehicle (100) in a non-contact manner by electromagnetic field resonance, and a device power feeding unit (184) for transmitting electric power to be supplied to an in-vehicle electrical device in a non-contact manner by electromagnetic induction. A distance over which the electric power is transmitted from an external power transmission unit (220) installed outside of the vehicle to the power reception unit (110) in a non-contact manner is longer than a distance over which the electric power is transmitted from the device power feeding unit (184) to the in-vehicle electrical device (400) in a non-contact manner. The vehicle (100) further includes a main battery (150) for supplying electric power to a motor generator (172, 174), and an auxiliary battery (182). The auxiliary battery (182) has a voltage lower than a voltage of the main battery (150). The device power feeding unit (184) receives electric power from the auxiliary battery (182) and transmits the power to the in-vehicle electrical device (400).
