Patent abstract
A thermal printhead (A1) includes electrodes (3a-3c) embedded in a glaze layer 2 at least at a portion laminated with a resistor (4). Favorably, the portion of the electrodes (3a-3c) laminated with the resistor (4) is sunk to a depth causing the surfaces of the electrodes to be flush with the surface of the glaze layer 2. Such structure enhances the heat transfer efficiency from a heating portion (40) of the resistor (4) to a thermal recording medium, and smooth transfer of thermal recording paper.
