Abstract
A power transmitting apparatus measures a waveform attenuation rate of a transmission power waveform, at a transmission antenna, in a state in which the power transmission by the power transmitting is restricted, sets a threshold used for detecting a foreign object between the power transmitting apparatus and the power receiving apparatus on the basis of the measured waveform attenuation rate, and determines whether or not the foreign object is present on the basis of the waveform attenuation rate measure after the threshold is set and the threshold.
