摘要： 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.

摘要： Disclosed herein is an antenna device that includes a first coil pattern having at least first, second, and third turns. As viewed in a coil axis direction, each of the first, second, and third turns has an opening with a width larger in a first direction than in a second direction orthogonal to the first direction. The width of the opening of the second turn in the second direction is larger than a width of the opening of the first turn in the second direction. The width of the opening of the third turn in the second direction is larger than the width of the opening of the second turn in the second direction and smaller than a width of the opening of the first turn in the first direction.
