Abstract
PURPOSE: To provide a thermal head improved in the wear resistant properties, the durability, and the resistance to crazing, by forming a beryllium oxide film as a protective film on a heating element.
CONSTITUTION: The beryllium oxide film 7 is formed on the heating element 3 provided on a substrate 1 with a partial glaze 2 therebetween. The beryllium oxide film is preferably formed as follows: metallic beryllium is charged into a closed crucible, heated to about 1,500°C, and then jetted into vacuum to form clusters of beryllium by the adiabatic expansion, and the clusters are ionized together with oxygen gas introduced near a jet nozzle of the crucible by electronic bombardment while the voltage is controlled to form single crystals of BeO clusters.
