Abstract
In a thermal head in which a heat generating portion is protruded by partially forming a glass glaze layer on an insulating substrate, a protruding portion is formed on the insulating substrate and the glass glaze layer is formed on the protruding portion. The heat generating portion can sufficiently be protruded to render the contact with the recording paper or ink ribbon favorable, thereby improving the heat efficiency.
