PROBLEM TO BE SOLVED: To provide a coil unit capable of reducing unnecessary leakage magnetic field, formed at a place separated from the coil unit, while suppressing decrease in power transmission efficiency.SOLUTION: A coil unit Lru1 includes a nonmagnetic conductor plate Sa arranged in the arrangement direction of first and second coils Lra, Lrb wound reversely from each other, and a magnetic material Fa. The magnetic material Fa has a first part F1A located on the outside of one outer contour of the conductor plate Sa in the arrangement direction of the first and second coils Lra, Lrb, and a second part F2A located on the outside of the other outer contour of the conductor plate Sa in the arrangement direction of the first and second coils Lra, Lrb. When viewing from the arrangement direction of the first and second coils Lra, Lrb, the first and second parts F1A, F2A are located on the side opposite from the side of the conductor plate Sa facing the first and second coils Lra, Lrb. |
