The power transmission device has: a transmission coil for supplying power to the power receiving device ; a power supply circuit for supplying AC power having an adjustable switching frequency to the power transmission coil ; and a control circuit that stops the power supply from the power supply circuit to the transmission coil when the non-contact power supply device does not perform a constant voltage output operation even if the switching frequency is changed over a predetermined frequency range.",
