Abstract
The size of an antenna coil is reduced and it is possible to prevent lowering of the reception sensitivity due to difference of the arrangement position of the antenna coil. On a winding frame (3) of a ferrite core (2), a first coil (5) and a second coil (6) are wound in such a manner that their winding axes orthogonally intersect each other, and a third coil (12) is wound around an outer circumference of the first coil (5) and the second coil (6), so that a winding axis is provided to be orthogonal to the winding axes of the first coil (5) and the second coil (6).
