<p>A thermal print head (A) comprises an insulating substrate (10) with upper and side surfaces (10a, 10b), and a glazed layer (11) formed to the substrate (10) for keeping heat. A heating resistor (13) is formed on the glazed layer (11). The thermal print head (A) futher includes a common electrode (12) and a plurality of individual electrodes. The common electrode (12) has a plurality of teeth (12a) for connection with the heating resistor (13) and a tie (12b) that connects the teeth (12a). An auxiliary electrode layer (14) is formed on the tie (12b). The heat resistor (13) and the auxiliary electrode layer (14) are covered with an overcoating layer (16), which is covered with a protective layer (17). The tie (12b) of the common electrode (12) directly touches both the glazed laer (11) and the upper surface (10a) of the substrate.</p> |
