The object of the present invention is to provide a panel-type heating element having an excellent durability and high effectiveness in electric power saving To attain said object, the present invention provides a panel-type heating element consisting of a base and a thin film containing zinc oxide and tin oxide formed on said base. Said panel-type heating element is advantageously manufactured by a method comprising spraying a solution containing a zinc compound and a tin compound which give oxides respectively by heating in a high temperature reaction chamber to form a thin film consisting of sediment containing zinc oxide and tin oxide on the surface of said base. Said thin film has excellent acid, water and chemical resistance, and heats quickly.
