Abstract

PURPOSE:To reinforce an ejecting end edge and prevent the deformation, etc. of an ejecting port due to the breaking of the ejecting end edge by bevelling the ejecting end edge, a section thereof is a knife edge-shaped, in a nozzle plate mounted to an ink injecting head. CONSTITUTION:A substrate 1, to both surfaces thereof silicon oxide films are formed and to one surface thereof a corrosion window conforming to a nozzle hole pattern is made up, is immersed in an anisotropic etching liquid, a pyramidal corrosion hole is built up from the corrosion window, a nozzle hole 2, a section of an ejecting end edge 3 of an ejecting port 2a thereof is knife edge-shaped, is formed and the nozzle plate is immersed in an etching liquid, volume ratio thereof is, for example, hydrofluoric acid:nitric acid:acetic acid=1:4:3, for a fixed time. Thus, the ejecting end edge 3 is corroded at speed faster than the surface of the substrate 1 and the surface of a circumferential wall of the nozzle hole, the ejecting end edge 3 is bevelled and the ejecting end edge 4, a section thereof is rounded, is made up.
