ABSTRACT:
The shape of a localized glaze layer strip for a thermal head is appropriately and suitably formed. A thermoplastic insulating layer is formed on a predetermined area of a substrate, and an unnecessary portion of the insulating layer is removed so as to leave a predetermined portion forming an insulating layer strip having a uniform width. The insulating layer strip is heated at a temperature higher than the softening point thereof for chamfering the corner edges. Finally, a heating element is formed on the top of the insulating layer strip.
