Abstract:
A thermal head comprising:a protection layer having mutually opposed first and second surfaces, said first and second surface being protruded toward a printing surface which is brought into contact with a heat sensitive record medium and is protruded from the remaining portion of the first surface of the protection layer and a part of said second surface being also protruded toward the printing surface according to the first surface;a heat generating section provided on said second surface of the protection layer at said protruded portion and including heat generating resistors and electrodes connected to the heat generating resistors for generating heat to be transferred to said heat sensitive record medium through said printing surface of the protection layer;a driving circuit connected to said electrodes of the heat generating section for supplying a heating electric power to the electrodes; anda reinforcing layer made of a material different from a material of said protection layer and provided on said first surface of the protection layer except for said printing surface such that a surface of said reinforcing layer is not higher than said first surface of the protection layer at said protruded printing surface.
