<p><P>PROBLEM TO BE SOLVED: To provide a high performance contact-less power receiving element capable of contriving countermeasures to noise in the case of signal transmission in accordance with an impressed magnetic field that is required for power transmission miniaturizing the contact-less power receiving element to the utmost without imparting other components and by which sufficient power and an electric signal can be obtained. <P>SOLUTION: The element is used as a secondary side coil of a contact-less power transmitter and constituted by comprising a coil CAP for power reception, that is constituted by winding conductor wire by defining a material part with high relative permeability in a coupled magnetic body 1 constituted by coupling and arranging magnetic materials with different relative permeability in serial as a first magnetic core 2, a first part C1 that is constituted by winding the conductor wire by defining a material part with low relative permeability in the coupled magnetic body 1 as a second magnetic core 3 and a second part C2 that is constituted by winding the conductor wire on one end part of the magnetic core 2 on which the coil CAP for power reception is formed close to the first part C1 and providing a coil CAS for reception that is constituted by equipping the parts C1, C2 in serial on winding the wire on each of the parts C1, C2 in the reverse direction so that the parts C1, C2 have reverse polarity. <P>COPYRIGHT: (C)2003,JPO</p> |
