ABSTRACT:
A nozzle plate free from stray fly and defective jetting is achieved by a method which has a first step of putting a photosensitive resin film 5 in pressure contact with a back surface of a nozzle plate 1. A part of the photosensitive resin film 5 is caused to step into a nozzle 4 by controlling the viscosity thereof by changing temperature. Then, the thus processed photosensitive resin film 5 is hardened by injecting ultraviolet rays thereto. Next, a front surface 2 of the nozzle plate 1 is subjected to a eutectoid plating 6 process. By regulating a step coverage d of a part of the eutectoid plating 6 into the nozzle 4 by the hardened photosensitive resin film 5, a-nozzle plate having consistent nozzles, each being free from stray fly and defective jetting can be formed.
