ABSTRACT:
A circuit terminal of a thermal head substrate is connected to a flexible printed circuit by an electroconductive adhesive or a solder metal. An overcoating composed of an insulating or extra-low electroconductive material is applied to cover a region containing a connected portion between the circuit terminal and the flexible printed circuit and to cover an exposed portion of the circuit terminal to thereby prevent corrosion of the circuit terminal, improve the mechanical strength of the flexible printed circuit connection, and prevent a short-circuit.
