Abstract
A power transfer system includes a power transmitting device and a power receiving device that are opposed to each other with sandwiching a medium therebetween. The power transmitting device transmits electric power at a resonance frequency that is determined by an impedance of an electric power transmission path including the power transmitting device, the power receiving device, and the medium.
