COIL UNIT AND WIRELESS POWER TRANSMISSION DEVICE
First Claim
1. A coil unit which wirelessly transmits power from a transmission side to a power receiving side, comprising:
- first and second coils in which directions of magnetic fields generated when a current flows are reversed to each other, and are apposed;
a non-magnetic conductive plate which is disposed along an arrangement direction of the first and second coils; and
a magnetic body,wherein 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 arrangement direction, and a second portion which is positioned in an outer side than an outline of the other side of the conductive plate in the arrangement direction, andwherein when viewing from the arrangement direction, the first and second portions are positioned on a side of the conductive plate where is opposite to a side which faces the first and second coils.

Abstract
A coil unit includes a non-magnetic conductive plate which is disposed in an arrangement direction of first and second coils have reverse winding direction to each other, 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 arrangement direction of the first and second coils, and a second portion which is positioned in an outer side than an outline of the other side of the conductive plate in the arrangement direction of the first and second coils. When viewing from the arrangement direction of the first and second coils, the first and second portions are positioned on a side of the conductive plate where is opposite to a side which faces the first and second coils.
