1. A portable device, comprising:
- an outer wall member exposed to outside;
a power-receiving module at least partially arranged along a surface shape of the outer wall member, which receives power supplied by means of a resonance phenomenon; and
an electronic device disposed in a magnetic field space formed by the resonance phenomenon so as to have a magnetic field strength weaker than that in other portions.

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.
