Abstract
A method for producing a liquid discharge head provided with a head main body including plural energy generating elements for generating energy for discharging liquid as a flying liquid droplet, and plural liquid paths in which the energy generating elements are respectively provided, and an orifice plate adjoined to the head main body and provided with plural discharge ports respectively communicating with the liquid paths and plural independent projections formed around the discharge ports and respectively corresponding to the discharge ports so as to enter into the liquid paths and to engage therewith. The method includes steps of forming the plural projections and the discharge ports while a continuous resinous film is transported; separating the film in a continuous manner in a predetermined size including the portion on which the discharge ports are formed, thereby preparing the orifice plate; and adjoining the orifice plate to the head main body.
