Zusammenfassung: | A heater device is provided with: a transparent substrate; a heating wire arranged on a first face side of the transparent substrate; and a transparent adhesive layer formed on the first face side of the transparent substrate so as to cover the heating wire. The values of the thickness and viscosity of the adhesive layer are selected such that, when the heater device is affixed onto a windshield by means of the adhesive layer, a wedge angle of a concave portion that is formed on the transparent substrate in the vicinity of the heating wire due to a height of the heating wire is no greater than 0.1°. |
