摘要：
A power feeding coil unit includes a power feeding coil, and first and second auxiliary coils located outside of the region defined by a wire of the power feeding coil. The axis of the first auxiliary coil and the axis of the second auxiliary coil are substantially perpendicular to the axis of the power feeding coil. The power feeding coil and the first and second auxiliary coils simultaneously generate respective magnetic fluxes, each of which interlinks the corresponding one of the power feeding coil and the first and second auxiliary coils in a direction from the center to the outside of the power feeding coil unit.
