An electric power transmission device contactlessly transmits electric power to an electric power receiving device. The electric power transmission device includes an inverter, a power transmission unit and an electronic control unit. The electronic control unit is configured to determine whether a current phase of output current flowing from the inverter to the power transmission unit leads output voltage, and adjust a frequency of the AC power in a direction to reduce a lead angle of the current phase when leading of the current phase relative to the output voltage is detected.
