A thermal printhead (A) which can enhance a pasting accuracy between a heating substrate and a radiation sheet in the thermal printhead and which comprises the radiation sheet (1) and the heating substrate (2) formed on the front surface thereof with a printing heating resistor (4) and mounted on the upper surface of the radiation sheet, wherein identification marks (M) each working as a positioning reference when mounting the substrate (2) on the sheet (1) are provided on the substrate (2) with a specified distance from the resistor (4) and each mark (M) has a shape having a vertical side (M1) aligned with a positioning reference line (D) which is vertical to an arrangement direction (X-axis direction) of the heating resistor of the substrate (2).
