Abstract
A rectifier circuit rectifies a current that flows through a reception coil. A smoothing capacitor is connected to the output of the rectifier circuit. A judgment unit generates a notification signal that corresponds to a comparison result obtained by comparing the voltage VRECT across the smoothing capacitor with a predetermined threshold voltage at a judgment timing. The judgment timing is positioned after the start of reception of a signal from a power supply apparatus.
