A contactless electric power transmission system includes an electric power reception device and a control device. The electric power reception device receives electric power transmitted in a contactless manner between the electric power reception device and an electric power transmission device. The control device sets, in a coupling zone in which a coupling degree between a primary side coil of the electric power transmission device and a secondary side coil of the electric power reception device is equal to or more than a predetermined degree, a communication zone in which the coupling degree is relatively small, and an electric power transmission zone in which the coupling degree is relatively large. The control device transmits information relating to electric power transmission in the electric power transmission zone from the electric power reception device to the electric power transmission device by communication between the electric power transmission device and the electric power reception device when the secondary side coil is present in a foremost communication zone of the coupling zone.
