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 (81) wound by an electric wire; and a magnetic pole core part (80) constituting a magnetic pole portion provided at both sides of the winding core part. A height of the uppermost part of a ferrite plate (80) 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 (50) wound around the winding core part (81), 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 (50) wound around the winding core part (81). A magnetic gap length D2 can be reduced while maintaining the mechanical gap length D1, thereby the inter-coil coupling factor is improved, and the power feed efficiency and the maximum feed power are increased.
