Abstract:
A method of manufacturing an ink-jet printer head having a substrate provided with a plurality of energy generating elements for generating pressure energy for ejecting inks and an orifice plate located on said substrate and having a plurality of ejection nozzles formed therein for ejecting inks in a predetermined direction by pressure generated by said energy generating elements, said method comprising the steps of:preparing a thin film sheet material having adhesive layers respectively formed on top and bottom sides, as a material of said orifice plate; removing one of said adhesive layers which is on an ink-ejecting-side surface of said thin film sheet material; forming an etching mask film on said ink-ejecting-side surface of said thin film sheet material from which said one of said adhesive layers has been removed; forming a pattern corresponding to said plurality of ejection nozzles on said mask film; and forming said plurality of ejection nozzles by dry etching in accordance with said pattern.
