WIRELESS POWER SUPPLY SYSTEM
First Claim
1. A wireless power supply system configured to transmit power as magnetic field energy from a power supplying resonance coil to a power receiving resonance coil by resonating the power supplying resonance coil with the power receiving resonance coil, whereina coil diameter of the power receiving resonance coil is made smaller than a coil diameter of the power supplying resonance coil.

Abstract
A wireless power supply system transmits power as magnetic field energy from a power supplying resonance coil to a power receiving resonance coil by resonating the power supplying resonance coil and the power receiving resonance coil. The coil diameter of the power receiving resonance coil is set smaller than the coil diameter of the power supplying resonance coil. Then, electromagnetic coupling between the power supplying resonance coil and the power receiving resonance coil is maintained in a stable state, and a space region where power can be transmitted in a state wherein power transmission efficiency is stabilized is expanded.
