First Claim
Patent Images
1. A power-receiving device comprising:
- a power-receiving resonance coil which receives power by a resonance phenomenon of resonance with a power-supplying module;
a power-receiving coil configured to receive the power from the power-receiving resonance coil; and
a magnetic member which at least in part overlaps the power-receiving resonance coil in a radial direction in order to increase or decrease magnetic coupling in the resonance.

Abstract
Transmission efficiency is increased or decreased by a simple arrangement. A power-receiving resonance coil to which power is supplied by a resonance phenomenon of resonance with a power-supplying module, a power-receiving coil which receives the power from the power-receiving resonance coil, and a magnetic member which at least in part overlaps the power-receiving resonance coil in a radial direction in order to increase or decrease magnetic coupling in resonance are provided.
