Abstract: A heat generating glass panel includes a window glass, a plurality of surface films coated and electrically generating heat on a surface of the window glass, and electrically separated from each other by a dividing line, and a plurality of electrodes connected to the surface films to apply heat generating voltages thereto, wherein the surface films include a central surface film and an outer surface film on the surface of the window glass, and wherein the voltages of the electrodes are adjusted in such a manner that a heat generation per unit area of the outer surface film is higher than a heat generation per unit area of the central surface film.
