<p>A non-contact power feeding device 1 feeds power from a power transmission coil 3 to a power receiving coil 5 based on a mutual induction effect of electromagnetic induction. In such a non-contact power feeding device 1, power can be fed to the power receiving coil 5 by a mobile power feeding method whereby the power receiving coil 5 is moved corresponding to the stationary power transmission coil 3 through an air gap A in the case of power feeding. The power transmission coil 3 and the power receiving coil 5 are respectively formed in a loop-shaped flat structure. A crossover coil C is adopted (to serve) as the power transmission coil 3. The crossover coil C is formed in a long loop shape along the direction of movement B of the power receiving side and is crossed along the way to provide a plurality of units D. It is however to be noted that a resonant repeating coil 17 can be used together with the power transmission coil 3 to adopt the crossover coil C as its repeating coil 17.</p>
