Abstract
Official abstract text for this publication.
In an antenna coil including a first magnetic core, a second magnetic core, and a flexible board, coil conductors are provided on a surface of the flexible board. By winding the flexible board around the first magnetic core and the second magnetic core, a first coil portion is disposed around the first magnetic core, and a second coil portion is disposed around the second magnetic core. The winding direction of the second coil portion is opposite to that of the first coil portion. The first coil portion and the second coil portion are connected to define one coil as a whole.
