The power transfer system includes a power transmission device and a power reception device disposed in the vehicle. The power transmission device includes a power transmission coil configured to transmit power in a wireless manner to the power reception device, an inverter configured to generate an AC transmission power and supply it to the power transmission coil, and a power supply ECU. When the transmission of power to the power reception device is started, the power supply ECU sets the transmission power at the start o power transmission to a first power which is lower than a second power, and performs the operating point search control in that state. If the reception power is lower than a tai et reception power after the operating point search control is completed, the power supply ECU sets the transmission power to the second power which is higher than the first power.
