Abstract
The object of the invention is to enhance precision in bonding the heating board and the radiating plate of a thermal print head, in the thermal print head A composed by attaching the heating board,on the surface of which a heating resistor for printing,is formed on the upper surface of the radiating plate,, an identification mark M that functions as a positioning reference when the heating board,is attached on the radiating plate,is provided on the heating board,at a fixed interval from the heating resistor,and in addition, the identification mark M has a vertical side M,equivalent to a positioning reference line D perpendicular to a direction in which the heating resistor of the heating board,is arranged (the direction of the x-axis).
