<p>A thermal printing head according to the present invention comprises an insulating head substrate (8) having a front (8a), a back (8b), a first longitudinal edge (8c) and a second longitudinal edge (8d). Formed on the front (8a) of this head substrate (8) are series of heat generating dots (10a) along the first longitudinal edge (8c), a common electrode pattern (11) adapted to be electrically connected to the series of heat generating dots (10a) in the vicinity of the first longitudinal edge (8c) and individual electrodes (12) extending in a direction in which they are separated from the common electrode pattern (11) and adapted to be electrically connected to the respective heat generating dots (10a). The heat generating dots (10a) are selectively activated by a driving element for generating heat. The common electrode pattern (11) is electrically connected to an auxiliary electrode layer (14) covering at least the first longitudinal edge (8c), the back (8b) and the second longitudinal edge (8d) of the head substrate (8).</p> |
