本発明は、部分グレーズ層が複数段積層され

On top of the partial glaze layer 3, a heating resistor film 4, an electrode 5, an oxidation-resistant protective layer 6, and an abrasion-resistant layer 7 are laminated.

も、記録紙が汚れると言う欠点があつた。 However, if the partial glaze layer is simply made higher as in the conventional thermal head, the shape near the heat generating part 2 tends to become flat. Therefore,
The adhesion between the thermal head and the recording paper deteriorated, and clear print quality could not be obtained. In order to obtain clear print quality, the thermal head must be strongly pressed against the recording paper, but this also has the drawback of staining the recording paper.

らびに印字エネルギーの低減が実現される。 FIG. 1 is a diagram showing the structure of a thermal head according to the present invention. An upper glaze layer 8 is integrally formed on top of the partial glaze layer 3 in a stacked manner on an insulating substrate 1 made of alumina or the like. This is formed by firing the partial glaze 3 and then printing and firing the upper glaze layer 8. On top of the partial glaze layer 3 and the upper glaze layer 8, a heating resistor film 4 made of a material such as Ta2N,
An electrode 5 made of a material such as Au, an oxidation-resistant protective layer 6 made of a material such as SiO2, and a wear-resistant layer 7 made of a material such as Ta2O5 are laminated. The structure of the thermal head of the present invention improves the close contact of the heat generating part 2 to the recording paper and the thermal ribbon, thereby realizing clear printing and reduction of printing energy.
本発明により発熱部付近のみが記録紙、もしく

まり、しかもほとんど、発熱部２のみが接触する
ために印字品質は更に向上し、印字エネルギーも
低減される。 According to the present invention, since only the vicinity of the heat generating part contacts the recording paper or the thermal ribbon, the adhesion is further improved, and since almost only the heat generating part 2 comes into contact, the printing quality is further improved and the printing energy is also reduced.
