Abstract: A power-supplying module and a power-receiving module are positioned so that a coil surface of a power-supplying resonator in the power-supplying module and a coil surface of a power-receiving resonator in the power-receiving module face each other. On the inner circumferential surface sides of the coils of the power-supplying resonator and the power-receiving resonator, cylindrical magnetic members and which cover the entire inner circumferential surfaces of the coil of the power-supplying resonator and the coil of the power-receiving resonator are arranged. When power transmission between the power-supplying resonator and the power-receiving resonator is performed, while varying the magnetic field, magnetic field occurring around the power-supplying resonator and the power-receiving resonator is shielded by the magnetic members. This improves power transmission efficiency of power transmitted from the power-supplying module to the power-receiving module, as compared with a case of arranging no magnetic members.

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.

Abstract: A wireless power transmission apparatus 1 includes a power-supplying module 2, a power-receiving module 3, a phase detector 4, and a control device 5, and is set so that its transmission characteristic with respect to the power-source frequency has a double-hump characteristic. The control device 5 determines whether to supply power to the power-supplying module 2, based on variation in the phase of the input impedance Zin in the power-supplying state and that in the standby state, which is detected by a phase detector 4.
