Abstract

PURPOSE:To enhance strength and durability without damaging the beneficial point possessed by an aluminum electrode, in a thermal head having heat gener ating resistor film and an electrode film, by forming the electrode film from a conductor based on Al. CONSTITUTION:In a thermal head wherein a heat generating resistor film 3 and an electrode film 4 are provided on an insulating substrate 1 composed of alumina, the electrode film 4 is formed from a conductor based on Al. This electrode film 4 is pref. formed from 99.5-90mol% Al and 0.5-10mol% Mg or 99.3-92mol% Al, 0.5-5mol% Mg and 0.2-3.0mol% Si. The membrane electrode material composed of a composition wherein a definite amount only of Mg or Mg and Si is added to Al as mentioned above has excellent capacities including durability as the electrode of the thermal head. When the conductor based on Al is used as the electrode material as mentioned above, the strength of the electrode material is increased and sufficient durability can be secured even when rough, hard and thick recording paper is used. Further, fine processing due to a photoresist etching process can be easily performed and mass productivity is also excellent.
