Abstract

The present invention provides a contactless power-feeding apparatus of which the degree of magnetic coupling with a pickup part is high to reduce the effect of a magnetic field and an electric field to the outside. The contactless power-feeding apparatus comprises: a pickup core 53 of a magnetic material provided with four legs 53a-53d erected almost in parallel at an appropriate interval to one side of a base 53e which is a rectangular plate, and pickup coils 51a-51c wound on the base 53e between the legs. Two homeward side feeder lines 2a and 2c are arranged in symmetry with respect to an outward side feeder line 2b.
