Original Abstract Submitted
A coil unit includes: an electric power reception portion of an electric power reception device mounted on a vehicle; and a control device. The electric power reception portion includes a secondary side coil and a secondary side capacitor that are connected in series. The secondary side coil receives an AC electric power transmitted in a contactless manner from the electric power transmission device. When receiving the AC electric power transmitted in a contactless manner from a primary side coil of the electric power transmission device, the secondary side coil that generates a reverse-phase current with respect to the primary side coil. A capacitance of the secondary side capacitor is set in accordance with a resonance point on a high frequency side of two resonance points in accordance with the secondary side coil and the secondary side capacitor.
