A ground-side coil unit is provided with: a magnetic material plate 12 disposed adjacent to a power transmission coil 11 that transmits electric power to a power reception coil 26 in a contactless manner; and a first filter coil 13 disposed opposing the power transmission coil 11 with the interposition of the magnetic material plate 12. The first filter coil 13 is disposed in a position in the magnetic material plate 12 where a magnetic flux 13G generated by the first filter coil 13 cancels out a magnetic flux 11G generated by the power transmission coil 11. |
