Abstract
PURPOSE: To obtain a thermal head which is highly reliable at a high speed and indestructible by a method wherein a protective layer is provided on the upper surface of a thin film resistance layer and a heat impact relaxing layer is fixed between said thin film resistance layer and the protective layer.
CONSTITUTION: A glass-glazing layer 2 is provided on an alumina substrate 1, on which a thin film heating resistance layer 3 is formed and, moreover, a lead electrode 4 is patterned by vacuum deposition, photoetching. Besides, after the protective layer 5 is provided by spattering, Ta2O5, Al2O3, etc. is formed by spattering to prepare a heat impact relaxing layer 7 and, moreover, a wear-proof layer 6 is provided to form a thermal head. When a heating resistance layer 3 is of Ta2N or Ta-Si, a heat impact relaxing layer can be formed by anode oxidation or thermal oxidation. This thermal head has a high reliability at a high speed and is useful as a recording head of facsimile or the like.
