Abstract
PURPOSE: To obtain a thermal head which has advantages of both a thick film type and a thin film type by laminating a thin film resistor on a thick film resistor to form a heating resistor and providing conductors on said heating resistor to form electrodes.
CONSTITUTION: A substrate 1 of alumina or the like is coated with a thin glaze layer 2, on which a thick film heating resistor 3 such as ruthenium oxide is provided by screen printing. It is desirable that said resistor 3 has a trapezoid cross-section and rectilinearly extends so as to contact with the extreme breadth of a thermosensitive recording paper by itself. The upper surface 3a and both inclined surfaces 3b are coated with a thin film heating resistor 4 of a chromium such as nickel chromium, nickel-chromium-silicon or chromium-silicon oxide by sputtering. Moreover provided are thin film conductors 7, 7... of gold, copper or the like which electrically connect the heating resistor 6 and thick film electrodes 5 respectively.
