PROBLEM TO BE SOLVED: To provide a non-contact power transmission system which enlarges the positional tolerance of an electric power receiver. SOLUTION: The non-contact power transmission system includes an electric power transmitter 1 which transmits electric power, and a movable electric power receiver 2 which receives electric power transmitted from the electric power transmitter 1 without contact, wherein the electric power transmitter 1 is equipped with a transmission coil 11 which transmits a high electric power between itself and the electric power receiver 2, and a communication coil 12 which communicates with feeble power, the electric power receiver 2 is equipped with a receiving coil 21 which receives electric power from the transmission coil 11 of the electric power transmitter 1, a plurality of coil groups 22 and 23 which communicate with the communication coil 12, and a control circuit which detects a coil in active state with the communication coil 12 among the plurality of coil groups.
