    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.

    Abstract: A coil unit includes a non-magnetic conductive plate which is disposed along an axis of a coil, and a magnetic body. The magnetic body includes a first portion which is positioned in an outer side than an outline of one side of the conductive plate in the axis direction of the coil, and a second portion which is positioned in an outer side than an outline of the other side of the conductive plate in the axis direction of the coil. When viewing from the axis direction of the coil, the first and second portions are positioned on a side of the conductive plate where is opposite to a side which faces the coil.

    Abstract: A coil unit includes first and second coils that are apposed, and third and fourth coils located on the rear side of the first and second coils so as to interpose the center of the first coil and the center of the second coil between the third and fourth coils, in the direction of alignment of the first and second coils. The axial direction of the third and fourth coils is substantially perpendicular to the axial direction of the first and second coils. First to fourth drive control units control the directions or phases of the currents to be supplied to the first to fourth coils, respectively.

    Abstract: Disclosed herein is a coil module that includes a holder having a flat-plate part for placing thereon a target device, a first stopper extending in a first direction along a first side of the flat-plate part, and a second stopper extending in a second direction orthogonal to the first direction along a second side of the flat-plate part; and a coil provided so as to overlap the flat-plate part of the holder. As viewed in a coil axis direction, an outer size of the coil in a third direction inclined at a predetermined angle with respect to the first direction is larger than an outer size of the coil in a fourth direction orthogonal to the third direction.
