Abstract
PURPOSE:To improve letter typing quality by providing an insulating base plate with a groove, laying a resistance in the groove and forming flat surfaces on the resistance and the electrode conductor so that thermal conduction to a heat-sensing recording paper becomes able to be achieved uniformly. CONSTITUTION:A groove 5, having a rectangular section of a required size and shape in one direction, is formed on an insulating base plate 1. This insulating base plate 1 is covered with gold or gold-chromium, and after completion of patterning by photoprinting process or screen printing to print a conductive paste, containing such metallic elements as silver-paradium and gold, etc., into a required pattern, a No.1 electrode conductor 6 is formed by drying and firing process. And then, a paste, prepared by mixing metallic element of lutetium oxide with glass frit in an organic solvent, is laid in the groove 5 to form a resistant 8. And further, an electrode conductor 7 is formed to cover the base plate 1 and a part of the resistant 8 in the same manner in which the electrode 6 was prepared.
