<P>PROBLEM TO BE SOLVED: To provide a non-contact power feeding device which enables the reduction of coil thickness, while ensuring a high coupling coefficient, large air gap and large power supply in a simple and easy way. <P>SOLUTION: In a non-contact power feeding device 22, electric power is supplied from a power transmission coil 3 in a power transmission circuit 19 to a power reception coil 8 in a power reception circuit 20 based on the mutual induction action of electromagnetic induction, with the coils positioned in a corresponding relationship without contact via an air gap. A resonance coil 16 of a relay circuit 15 is arranged on one or both of the power transmission coil 3 side and the power reception coil 8 side. The resonance coil 16 is wound in parallel to the power transmission coil 3 and the power reception coil 8 on the same plane. A single or multiple pieces of insulation coil conductors 26, 27 and 28 are used as one unit for the resonance coil 16, power transmission coil 3 and power reception coil 8, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
