In addition, in a thermal print head in which a protective film is formed on the heating resistor and the lead pattern, in order to improve the heat dissipation of the lead pattern on the paper ejection side, the lead pattern on the paper feed side and the paper ejection side are combined. A thermal print head characterized in that the lead pattern is set asymmetrically with respect to the center of the heating resistor.
