Abstract
Abstract A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X of forming a member a provided with a perforation for constituting said action chamber, a step Y of adjoining an end aperture of said perforation to another member b constituting an intermediate supply chamber of said liquid, and a step Z of attaching to said member c another member c for forming a slit in the vicinity of the other end aperture of said perforation.
