Abstract
A vehicle antenna device has a stably held coil element while its winding shape is maintained, and the number of turns of the coil element winding is easily adjusted during production. A coil element is configured by forming a winding around a resin-made bobbin. A guide groove, which is a path of the winding, and a plurality of projections, which are along the path of the winding, are disposed on the outer circumferential surface of the winding barrel of the bobbin. The guide groove spirally extends around the outer circumferential surface of the winding barrel. The projections are disposed in plural numbers in each of a plurality of circumferential positions on the outer circumferential surface of the winding barrel. A winding end portion of the winding is drawn out in the axial direction while being hooked to an arbitrary one of the projections, and electrically connected to an upper terminal.
