ABSTRACT:
A line-type thermal printing head comprises an elongate support plate, an elongate head substrate mounted on the support plate, and a strip-like auxiliary substrate mounted on the support plate to extend longitudinally of the head substrate. The head substrate is formed with a heating resistor line extending longitudinally of the head substrate, and a common electrode extending substantially in parallel to the resistor line adjacent to a longitudinal edge of the head substrate. The auxiliary substrate has a side surface which is substantially perpendicular to the head substrate and formed with a longitudinal conductor strip connected electrically to the common electrode through a conductive member.
