Abstract
In order to obtain a thermal head for a single power source drive with a good print efficiency and capable of performing high speed printing, semiconductor driver elements having a small on-resistance and a small output saturation voltage V.sub.CE are used, and in order to reduce a voltage drop V.sub.lead of each separate electrode, an inorganic gold paste as a separate electrode material is used to form a thick layer part. An electronic apparatus using the thermal head is also disclosed.
