Summary:A power reception coil of a non-contact power supply device includes a plurality of power reception coil windings arranged along a movement direction of a moving object, and the adjacent power reception coil windings are disposed so as to partially overlap each other. Accordingly, even if a power transmission coil is positioned at a boundary between the power reception coil windings, power supply performance does not decrease. In addition, one power reception coil winding is not opposed to two power transmission coils at a time, and thus a cancellation phenomenon of magnetic fields can be prevented and power can be stably supplied.
