A thermal printing head (10) comprises an insulating head substrate (11) having a first edge portion (11a) and a second edge portion (11b) positioned on an opposite side of the first edge portion, a heating resistor (12) formed on the head substrate (11) along the first edge portion (11a), at least one drive IC (13) mounted on the head substrate (11) along the second edge portion (11b), and a protective cover (20) mounted to cover the drive IC (13). The protective cover (20) comprises a cover portion (22) covering the drive IC (13), and a fixing portion (21) integral with the cover portion (22). The fixing portion (21) has a positioning wall (23) which directly abuts against the second edge portion (11b) of the head substrate (11), and is constructed so as to fix the protective cover (20) to the head substrate (11) without any separate fixing means. <IMAGE> |
