Antenna device for mounting on a printed circuit board

摘要

An antenna device (1) includes: a winding component (2) having an approximately cylindrical shaped winding shaft portion (10) and a flange portion (12,13) disposed to project outside the winding shaft portion in at least one end portion of both end portions in an axial direction of the winding shaft portion; a pair of binding terminals (22) disposed to project outside the flange portion in at least one of the flange portions; and a winding (4) both ends of which are bound to the pair of binding terminals. The flange portion on which the binding terminals are disposed has an approximate disk shape. At least one binding terminal is disposed to be oriented along a direction approximately perpendicular to an outer periphery of the flange portion on which the binding terminal is disposed.
