A contactless electric power transmission system includes a drive control device and an electric power reception device. The electric power reception device includes an electric power reception portion and a reception electric power conversion portion. The electric power reception portion includes a secondary side coil and a secondary side capacitor. The secondary side coil receives AC electric power transmitted in a contactless manner from the electric power transmission device. The secondary side capacitor is connected in series to the secondary side coil. The reception electric power conversion portion converts the AC electric power received by the electric power reception portion into DC electric power. A control device sets a drive frequency of the electric power transmission device such that an average electric power received by the electric power reception portion in an electric power transmission zone of an electric power transmission device is maximized.
