Claim:
1. A wireless power supply system comprising: a power sending resonance coil configured to have a resonance frequency characteristic and to transmit power wirelessly; a power receiving resonance coil configured to have the same resonance frequency characteristic with the power sending resonance coil and to receive power wirelessly under a magnetic field resonance mode generated by synchronization of a resonance frequency; one or more relay resonance coils configured to have the same resonance frequency characteristic with the power sending resonance coil and the power receiving resonance coil and to relay power from the power sending resonance coil to the power receiving resonance coil wirelessly under the magnetic field resonance mode generated by synchronization of a resonance frequency with the power sending resonance coil and the power receiving resonance coil, and a posture control apparatus that controls a direction of coil axis of at least one of the power sending resonance coil, the power receiving resonance coil and the relay resonance coil, wherein the power sending resonance coil is provided in a facility on which a plurality of electric devices can be placed, or in a ceiling, floor or wall of a room in which the plurality of electric devices exist.
