Abstract
When power transmitting electrodes of a power transmitting apparatus are respectively facing power receiving electrodes of a power receiving apparatus, a composite resonant circuit including a series resonant circuit and a parallel resonant circuit is formed through a compound capacitance formed between the power transmitting electrodes and the power receiving electrodes. In a predetermined mutually facing state in which the compound capacitance becomes maximum, the impedances of the configuration components of the composite resonant circuit are set such that a resonant frequency at which the impedance of the composite resonant circuit from a signal generator side when inputs of a load circuit is short-circuited becomes locally minimum, becomes higher than a resonant frequency at which the impedance of the composite resonant circuit as seen from the signal generator side when the inputs of the load circuit are open becomes locally maximum.
