Abstract

PURPOSE: To obtain a head which is less susceptible of a change and has specific resistance following the elapse of time by forming an oxidation film on the surface of a heating resistance consisting of tantaloxiniteride with regard to a thermosensitive recording head having a film heating resistance.
CONSTITUTION: On an insulative substrate 1 equipped with a glazed layer 3 on an alumina substrate 2, a film heating resistance 4 of tantaloxiniteride is spattered, and then an electric conductor 6 is arranged. Aluminium can be used as an electric conductor 6. Next, it is heated in an atmosphere at more than 300°C to form an oxidation film. In addition, a protective layer 7, 8 having oxidation resistance and wear-proofness such as SiO2, Ta2O5, etc. is formed and then is covered by an insulation 9. A thermal head formed in this manner is processed for stabilization at time of oxidation film formation. For this reason, an electric resistance change factor at less than working temperature is exteremely low.
