A contactless power transfer core used for a power transmission coil or a power reception coil of a contactless power transfer apparatus includes: a winding core part wound by an electric wire; and a magnetic pole core part constituting a magnetic pole portion provided at both sides of the winding core part. A height of the uppermost part of a ferrite plate arranged on a face of the magnetic pole core part at a side opposing a counterpart coil is equal to or greater than a height of an outer circumference of the electric wire wound around the winding core part, and a height of the ferrite plate of a face at a side not opposing the counterpart coil is lower than the height of the outer circumference of the electric wire wound around the winding core.
