Abstract
A power feeding coil unit includes a first power feeding coil and a second power feeding coil that generate a first magnetic flux, a first auxiliary coil that generates a second magnetic flux interlinking with the first power feeding coil, and a second auxiliary coil that generates a third magnetic flux interlinking with the second power feeding coil. An axial direction of the first auxiliary coil is nonparallel to an axial direction of the first power feeding coil, and an axial direction of the second auxiliary coil is nonparallel to an axial direction of the second power feeding coil. A direction of circulation of the second and third magnetic fluxes are opposite to a direction of circulation of the first magnetic flux.
