THERMAL HEAD AND METHOD OF MANUFACTURING THE SAME

摘要

A thermal head comprising an insulating substrate (1), a convex glaze layer (2) of amorphous glass formed on a surface of the insulating substrate (1), a heat generating resistance layer (5) formed on the convex glaze layer (2), an electrode forming glaze layer (3) formed on the surface of the insulating substrate (1) so as to overlap the convex glaze layer (2), and an electrode layer (4) formed on the electrode forming glaze layer (3) so as to overlap the heat generating resistance layer (5). The convex glaze layer (2) and the electrode forming glaze layer (3) are formed of amorphous glass. The electrode forming glaze layer (3) is formed to be thinner than the convex glaze layer (2), whereby the electrode forming glaze layer (3) can be formed at a lower temperature than the convex glaze layer (2).
