A wireless power transfer system includes a first power transmission unit, a second power transmission unit, a power reception unit, a sensing unit, and an ECU. The first power transmission unit is provided in a parking space. The second power transmission unit is provided in a traveling lane for a vehicle. The sensing unit senses a sensing target in a sensing region set around the vehicle. When the sensing unit senses the sensing target, the ECU reduces electric power transmitted from the first power transmission unit or the second power transmission unit that is transmitting electric power to the vehicle. The ECU sets the sensing region to be larger when the power reception unit receives electric power from the first power transmission unit than when the power reception unit receives electric power from the second power transmission unit.
