摘要:
A thermal printhead (A) according to the present invention includes a heating resistor (5) formed on a substrate (1), an electrode (3) for energizing the heating resistor (5), and a protection film (6) for covering the heating resistor (5) and the electrode (3). The protection film (6) has a surface with a ten-point mean roughness of no smaller than 0.2 μm.
