An inverter (220) generates transmission power at a prescribed frequency and supplies transmission power to a power transmitter (240). A power supply ECU (250) is configured to carry out turn-on current control for controlling a turn-on current (It) to a restriction value or less by manipulating a frequency (f) of transmission power by means of the inverter (220). Turn-on current control includes first processing for determining a direction of manipulation of the frequency (f) for lowering the turn-on current (It) based on a direction of variation in turn-on current (It) at the time when the frequency (f) is varied.
