PORTABLE DEVICE, CHARGING DEVICE FOR SAME, AND CHARGING SYSTEM FOR PORTABLE DEVICE

摘要

A portable device (1) has an outer wall member (12) exposed outside, and a power receiving module (11) at least a portion of which is arranged along the surface shape of the outer wall member (12) to receive power by way of the resonance phenomenon. The power receiving module (11) has a power receiving resonance coil (111) and a power extraction coil (112). The portable device (1) creates a small space for a magnetic field at the inner position or the peripheral position of the power receiving module (11) during power feeding using the resonance phenomenon so that an electronic device (13) is arranged in the space.
