Abstract
Provided is a power feeding system configured to supply electric power from a power feeding device to a power receiving device. The power feeding device includes: a feeding coil; a drive transistor; and a drive control circuit. The power receiving device includes: a resonant circuit including a receiving coil, a resonant capacitor, and a resonance control transistor; and a resonance control circuit. The feeding coil and the receiving coil are arranged so that a central axis of the feeding coil and a central axis of the receiving coil are orthogonal to each other, and a winding portion of the receiving coil is not positioned in a region of a magnetic flux parallel to the central axis of the feeding coil which is generated by the feeding coil.
