摘要： In a thermal printhead (A), a common wiring portion (4) is divided into a plurality of blocks (BL) arranged side by side in a primary scanning direction, and voltage is applied to opposite ends of each of the blocks (BL) in the primary scanning direction. A plurality of heating resistance sections (3) are divided into a plurality of blocks (BL′) corresponding to the blocks (BL) of the common wiring portion (4), and in each of the blocks (BL′), the resistance reduces as proceeding from opposite ends toward the center in the primary scanning direction. Therefore, the adjustment of the resistances of the plurality of heating resistance sections is easy, and the non-uniformity in darkness of print dots is reduced, so that high-quality image printing is possible.

摘要： A thermal head of the present invention includes an insulating substrate (1), a bulging glaze layer (2) of amorphous glass formed on a surface of the insulating substrate (1), a heating resistor layer (5) formed on the bulging glaze layer (2), an electrode-carrying glaze layer (3) formed on the surface of the insulating substrate (1) to partially overlap the bulging glaze layer (2), and an electrode layer (4) formed on the electrode-carrying glaze layer (3) to partially overlap the heating resistor layer (5). Each of the bulging glaze layer (2) and the electrode-carrying glaze layer (3) is made of amorphous glass. The electrode-carrying glaze layer (3) has a smaller thickness than the bulging glaze layer (2). Thus, it is possible to bake the electrode-carrying glaze layer (3) at a lower temperature than the baking temperature for the bulging glaze layer (2).

摘要： A method of manufacturing a thermal print head includes a conductor layer formation step, a first measurement step, a conductor layer splitting step and a second measurement step. In the conductor layer formation step, a single conductor layer including first and second measurement points is formed on a substrate. In the first measurement step, the electrical resistance is measured in the conductor layer, between the first and the second measurement points. In the conductor layer splitting step, a predetermined portion of the conductor layer is removed, so that a first electrode including the first measurement point and a second electrode including the second measurement point are formed. In the second measurement step, the resistance between the first and the second electrodes is measured. If the conductor layer has a disconnected portion in the first measurement step, a repairing conductor is formed on the disconnected portion.
