Claims

[Scope of utility model registration request]

It is equipped with an insulating base, on which a band-shaped continuous heating element is formed in the printing width direction, and this continuous heating element is individually connected to a current-carrying electrode for each printing dot unit, while a heating element formed by connecting to a common electrode is formed. In the print head, a first common electrode portion of the common electrode extending in the printing width direction on the upper surface of the base;
a plurality of second common electrode parts extending from the common electrode part in a direction perpendicular to the printing width direction at intervals from each other; and a plurality of printing dots extending from the first common electrode part in a direction opposite to the extending direction of the second common electrode part. forming a plurality of third common electrode parts for each unit; forming an insulating layer on the first common electrode part;
A plurality of fourth common electrode parts are formed along the vertical direction, parts of which individually overlap the common electrode part, and a plurality of current-carrying electrodes are formed along the vertical direction between these fourth common electrode parts. and a thermal printing head comprising a band-shaped continuous heating element connecting the fourth common electrode portion and the current-carrying electrode.
