Abstract
PURPOSE: To improve the resistance to wear and to extend the head life, by adding one or more additives to a film for protecting a heating body.
CONSTITUTION: When an SiO2 film 2 for protecting the heating body 4 is formed, Al2O3, etc. are incorporated therein, or when the Ta2O5 film 1 is formed on the SiO2 film 2, into the Ta2O5 are incorporated TiO2, ZrO2, WO3, etc. The resistance to wear can be improved, and since the thickness of the protecting film can be reduced, the spattering period can be shortened, and the arrangement can be produced at low cost.
