A thermal print head includes a substrate, a glaze layer formed on the substrate and provided with a heating resistor support portion extending in a primary scanning direction and having an arc-like cross-sectional shape when seen in a direction perpendicular to the primary scanning direction, an electrode layer including a plurality of individual electrodes, each provided with a first strip-shaped portion arranged along the primary scanning direction, each of the first strip-shaped portions formed on the heating resistor support portion, and a common electrode provided with a plurality of second strip-shaped portions arranged along the primary scanning direction, each of the second strip-shaped portions formed on the heating resistor support portion; and a resistor layer including heating portions heated by applying an electric current from the electrode layer and electrode covering portions each configured to cover a gap between the first and second strip-shaped portions. |
