Abstract: A heating device for heating a glass surface, such as the rear window of a car, includes a pair of elongated electrically non-conductive carrier strips having an adhesive layer on both sides thereof and secured in spaced-apart relationship to the glass surface by one of their adhesive layers to laterally delimit the surface area of the glass encompassed by the heating device. A plurality of spaced, thin electrically conductive foil strips, each cut in predetermined lengths from a continuous strip, and each of which has an adhesive layer on one side, extend between the carrier strips. The ends of the foil strips overlie the carrier strips and are secured to the carrier strips and the glass surface by the adhesive layer thereof. A strip-shaped electrical terminal conductor overlies each carrier strip in electrically conductive engagement with the foil strip ends and is fastened to the carrier strip by the other adhesive layer on the carrier strip exposed between the foil strip ends.
