Abstract
PURPOSE: To provide a thermal head which improves an oxidation resistance without thickening a film thickness and prevents exfoliation of a heating device, by a method wherein an oxygen absorbing layers is placed between upper and lower oxygen insulation layers to form an oxidation-resistant protection film, and the film is formed on a heating resistor.
CONSTITUTION: A lower oxygen insulation layer 4 and an upper oxygen insulation layer 6 are formed, and an oxygen absorbing layer (preferably a spatter or film made of Ta, Zr, Hf, Si, Cr, Ti) is laid between the two layers 4 and 6 to form an oxygen-resistant protection film. Said oxygen-resistant protection film is placed on a base board having a heating resistor 2 and an electrode 3, and an abrasion- resistant layer 7, made of Ta2O5, SiC or the like, is placed thereon where necessary to obtain a desired heat-sensitive recording head.
