摘要： A thick-film thermal printhead comprises: an oblong rectangular substrate (1) having at least one longitudinal edge (1a); a partial glaze layer provided on the substrate along the longitudinal edge; a linear heating resistor (11) formed on the partial glaze layer; a common electrode (12) formed on the substrate and electrically connected to the heating resistor; and a plurality of individual electrode (13) formed on the substrate and electrically connected to the heating resistor. The common electrode includes a plurality of comb-like teeth (12A). Each of the comb-like teeth includes a tip portion (12c) having a smaller width and a base portion (12d) having a larger width. Each of the individual electrodes includes a tip portion (13d) having a smaller width and an intermediate portion (13e) having a larger width.
