摘要： A feed element is disposed over a surface of a first conductor. A second conductor is disposed at a distance from the feed element greater than a distance between the feed element and the surface. The second conductor has a second shape that is a sheet-like shape in plan view. The second conductor is disposed to overlap the surface of the feed element. At least a part of the third conductor is located closer to the first conductor than the second conductor is located, in a direction perpendicular to the surface of the second conductor. The at least part of the third conductor is located farther than a part of the second conductor with respect to the feed element. A second distance between the at least part of the third conductor and the first conductor is less than twice a first distance between the feed element and the first conductor.
