Abstract
A portable device has an outer wall member exposed outside, and a power-receiving module at least a portion of which is arranged along the surface shape of the outer wall member to receive power by way of the resonance phenomenon. The power-receiving module has a power-receiving resonance coil and a power-drawing coil. The portable device creates a space portion with a weak magnetic field at the inner position or the peripheral position of the power receiving module during power feeding using the resonance phenomenon so that an electronic device is arranged in the space.
