Power supplier and receiver and mobile device

Abstract

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 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, and this magnetic field space is used as the arrangement place of an electronic component. The power-receiving module includes a power-receiving resonance coil which is resonated with a power-supplying module and a power-receiving coil which partly overlaps the power-receiving resonance coil in a coil diameter direction and receives and supplies power from and to the power-receiving resonance coil.

1 . A power-supplying device comprising:
 a power-supplying module configured to supply power to a power-receiving module by a resonance phenomenon; and   an electronic component being at least partly provided in a magnetic field space which is formed by the resonance phenomenon to have a lower magnetic field strength than other parts, wherein   the power-supplying module includes:
 a power-supplying resonance coil which is resonated with the power-receiving module; and 
 a power-supplying coil which at least partly overlaps the power-supplying resonance coil in a coil diameter direction and is configured to supply power to the power-supplying resonance coil. 
   
     
     
         2 . The power-supplying device according to  claim 1 , wherein the electronic component includes at least one of an AC/DC converter, a charging unit, and a controller. 
     
     
         3 . The power-supplying device according to  claim 1 , wherein each of the power-supplying resonance coil and the power-supplying coil is a solenoid coil. 
     
     
         4 . A portable device comprising the power-supplying device according to  claim 1 . 
     
     
         5 . The portable device according to  claim 4 , further comprising an outer wall member exposed to the outside, at least a part of the power-supplying module in the power-supplying device being provided along a surface shape of the outer wall member. 
     
     
         6 . A power-supplying device comprising:
