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).
