PROBLEM TO BE SOLVED: To prevent a resin holder from thermally deforming by suppressing the heat supplied to base units from transferred to a resin holder side, when the base unit with which a high frequency coil is connected or the base units, on which the resin holder is fixed is soldered on a bus bar for a heating wire. SOLUTION: A high-frequency coil is assembled by soldering on a bus bar of a heating wire for preventing fogging of a glass antenna, which is provided with a heating wire for preventing fogging on the rear window glass of a vehicle and a high-frequency antenna pattern at a peripheral space. The high-frequency coil is provided with small section areas on a coil fixing base of a high-frequency coil, which is insulated and covered by a resin holder and/or on the fixing base of the resin holder respectively. Thermal deformation of the resin holder due to conductive heat during soldering is prevented by the small section area, and the small section areas are made to have a constricted shape, a through-hole, a thin thickness or combinations of these.
