POWER SUPPLIER AND RECEIVER AND MOBILE DEVICE

摘要

An arrangement place for a device such as a rectifier and a power storage device is easily secured. At the time of power supply using a resonance phenomenon, a power-receiving device 1 generates a magnetic field space having a lower magnetic field strength than other parts at or around the inner side of the power-receiving module 11, and this magnetic field space is used as the arrangement place of an electronic component 13. The power-receiving module 11 includes a power-receiving resonance coil 111 which is resonated with a power-supplying module 21 and a power-receiving coil 112 which partly overlaps the power-receiving resonance coil 111 in a coil diameter direction and receives and supplies power from and to the power-receiving resonance coil 111.
