Abstract

PURPOSE:To reduce the variations of resistance values of heating resistors and achieve the evenness of printing densities by forming wiring patterns, then forming conductive thick film layers only on bonding and soldering portions. CONSTITUTION:After heating resistor 2, first, second conductive thin films 3, 4 are formed on an insulation type substrate 1, wiring patterns are photoetched. Therafter, electroplating is performed with the second thin film layers 4 having remained on the patterns necessary for bonding or soldering as a cathode, forming conductive thick film layers 5 such as of Au or other thereon. And in order to prevent alloying of the heating resistors 2 and the thin film layers 4, only the thin film layers 4 and thik film layers 5 are partly etched away so as to cross the wiring patterns and in order to form the heating parts within the remained first thin film layers 3, the thin fm layers 3 are partly etched away. Thereby, the variations of pattern sizes and the variations of the resistance values of the heating resistors may be reduced and the printing densities evened.
