Abstract

PURPOSE:To prevent breakage of the head due to its longer employment and to prevent the resistance value thereof from changing thereby to improve its life, by selectively removing in a prescrived depth a glaze layer underlaying a silicon heating body layer on which leading layers are laid. CONSTITUTION:In the silicon thin film heating head 1 comprising the polycrystalline silicon thin film heating body layer 4 and the leading layers 51, 53 overlaid on the vitreous glaze layer 3 for the accumulation of heat on a base plate 2 of alumina or the like and covered with a protective film 6, the glaze layer is selectively removed in a prescribed depth and in a prescribed region below an end of the heating portion side of at least one of the leading layers. For example, a part of the glaze layer that is located just below an end of the heating portion side of the leading layer 51 and a part adjacent to said first part are removed crosswise with respect to each member of the heating body layer 4. Said depth is equal to or more than the thickness of the leading layer 51.
