In a non-contact power feeding apparatus of the present invention, power is fed through an air gap from a power transmission coil of a power feeding side circuit to a power receiving coil of a power receiving side circuit, which are closely located to face each other, based on a mutual induction effect of electromagnetic induction. The power transmission coil and the power receiving coil are respectively composed of a planar assembly of a number of unit coils. Each unit coil is formed in a spirally wound flat structure, wherein the direction of an electric current is set in reverse to make the north and south magnetic poles reverse between each unit coil which is juxtaposed to another to directly come into line. As a result, the unit coils, which are juxtaposed to another to directly come into line, are provided in such a manner that an overlapping area of a respectively formed magnetic field cancels another out to be offset |
