Abstract
PURPOSE:To improve the efficiency and life of recording by a method wherein a heating resistor layer is provided on the upper part of a wiring conductive layer which heating resistor zone is changed by anodic oxidation processing into a non-conductor and then a protective layer is provided. CONSTITUTION:An undercoat film 7 is laminated on a glazed ceramic base 6 in order to protect the base from erosion by etching liquid and, besides, a wiring conductive layer 9 is laminated and provided by Al-vacuum deposition method. And, this Al conductive layer is pattern-formed by photoetching in the form of a thermal print head. Thereafter, a zone wherein the heating resistor 1 is formed is patterned by a photoresist 13 so that the zone only may be exposed. A non-conductive layer 14 is formed on this exposed zone only by the anodic oxidation processing, then, after the photoresist film 13 is separated the heating resistor layer 8 is provided so that it may be stacked on the peripheral conductive layer 9 and finally a protectve layer 10 is formed to complete the head.
