Abstract: The size of an antenna coil is reduced, and it is possible to prevent a lowering of the reception sensitivity due to a difference of the arrangement position of the antenna coil. On a winding frame of a ferrite core, a first coil and a second coil are wound in such a manner that their winding axes orthogonally intersect each other. A third coil is wound around an outer circumference of the first coil and the second coil in such a manner that the third coil's winding axis orthogonally intersects the winding axes of the first coil and the second coil.
