Abstract
A thermal head including a protection layer having mutually opposed first and second surfaces, said first surface having a flat or protruded printing surface which is brought into contact with a heat sensitive record medium, a heat generating section including resistors and electrodes connected to the electrodes and provided on said second surface of the protection layer, and a reinforcing member made of a low melting pint glass and provided on a side of the heat generating section remote from the protection layer. The reinforcing member improves a mechanical strength of the thermal head. The reinforcing member made of a glass also serves as a heat storage member, and thus a thermal property of the thermal head is improved. The reinforcing member may be formed by an aggregate of ceramic particles. The reinforcing member may contain a heat storage layer made of a low melting point glass and a heat conduction layer provided on the heat storage layer.
