ABSTRACT:
The present invention provides a thermal head including a substrate of alumina, a glaze layer formed on the substrate and patterning resistor and electrode layers on the glaze layer. The thermal head is of a whole glaze type in which a heating section is formed on the glaze layer at or adjacent to the edge portion thereof or of a partial glaze type in which a heating section is formed on the glaze layer at or adjacent to its partially cut edge portion. Thus, the thermal head can print more clearly.
