A contactless power transmission system includes a power reception unit configured to receive AC power contactlessly transmitted from a power transmission device, a power conversion unit configured to convert the AC power into DC power, a power storage device connected to the power conversion unit, a rotating electric machine configured to generate a traveling driving force of a vehicle and to transmit and receive power to and from the power storage device, and a control device configured to control an operation of the power conversion unit and power transmission and reception between the power storage device and the rotating electric machine, wherein the control device restricts reception of the AC power by the power reception unit when a state of charge of the power storage device is larger than a predetermined threshold value, and changes the predetermined threshold value to decrease as a speed of the vehicle increases.
