Abstract
An antenna coil includes: an air-core type flat coil body; and a coil support member disposed between the coil body and a substrate so that the coil body is supported on a surface of the substrate. The thickness of the coil body is smaller than a radius of a circle, an area of which is equal to an area of a region surrounded with an outline of a projected coil body, the projected coil body provided by projecting the coil body on a projection plane perpendicular to the axial direction of the coil body. The coil support member is made of resin hardened soft magnetic material.
