A power transmitter provided according to one aspect of the present disclosure includes a high-frequency power source device, a power transmitting unit, and a transmitter-side controller. The high-frequency power source device generates high-frequency power. The power transmitting unit includes a power-transmitting coil. The power transmitting unit wirelessly transmits the high-frequency power received from the high-frequency power source device to a power receiver mounted on an electric vehicle. The transmitter-side controller calculates a transmitter usage rate. The transmitter-side controller causes the power transmitting unit to stop power transmission in response to the transmitter usage rate exceeding a predetermined threshold. The transmitter usage rate indicates a rate of time during which the power transmitting unit transmits power to the power receiver per unit time.
