An individual electrode 3, common electrode 4, and heating body 5 are provided on a ceramic base plate 1. An insulating protective film 6a is formed on the heating body 5. Further, a conductive protective film 7 is formed on the insulating protective film 6a, said film being with higher thermal conductivity than that of the insulating protective film 6a. The conductive protective film 7 and the common electrode 4 are connected electrically. Affect of static electricity caused by charged electricity with the thermal sensitive paper can be prevented as a protective film which is a point of contact with the thermal sensitive paper 8 is made of a conductive protective film 7 and connected to a common electrode. Deterioration due to abrasion with the thermal sensitive paper carried while pressurized by a platen roller 9 can be prevented and anti-abrasion can be improved as temperature of the conductive protective film which is a point of contact with the thermal sensitive paper 8 maintains temperature which contributes the coloring and also is suppressed at a lower average level.
