A resonance coil (210) receives electric power without contact from a resistance coil (140) included in an electric power feeding apparatus (100) outside a vehicle by resonating with the resonance coil (140) via an electromagnetic field. An electromagnetic induction coil (220) takes, by electromagnetic induction, the electric power received by the resonance coil (140) and outputs it to a rectifier circuit (230). A detecting coil (270) takes, by electromagnetic induction, the electric power received from the resonance coil ( 140), and is configured such that a degree of electromagnetic coupling with the resonance coil (140) is smaller than it is with the electromagnetic induction coil (220). |
