Abstract

PURPOSE:To prevent corrosion and to make printing always normal, by covering the part which is not covered with an oxidation preventing layer, of the pattern comprising an electric good conductor other than gold formed on a heat generating substrate with a material composed of a metal or a semi-metal. CONSTITUTION:A conductor lead 2 composed of an electric good conductor other than gold is formed on a heat generating substrate 1 through a heat- generating resistor 3, and a resistor-protecting layer 4 and an oxidation- preventing layer 5 protecting the heat-generating resistor 3 from abrasion and oxidation are further formed. Further, the exposed part of the conductor lead 2 is covered with a material layer 6 composed of a metal or a semi-metal to form a thermal head. Because this thermal head is constituted so that the conductor lead 2 having an electric good conductor other than gold such as Al, Cu, Ag, Ni or Sn is covered with the metal or semi-metal having high corrosion resistance, the corrosion of the conductor lead 2 is prevented to enable normal printing.
