Abstract

PURPOSE: To produce a nozzle plate having sufficient mechanical strength, durability and high precision, by covering the nozzle and opening part and surface of reinforcing plate with wear resistant metal.
CONSTITUTION: On one side of a reinforcing plate 1 made of copper alloy, a photo resist body 2 of which outside diameter is nearly equal to the inside of nozzle part is formed by a thickness slightly larger than the length of desired nozzle part, and on the other side, a same photo resist film 2' or other film is formed on the entire surface. On the exposed part of the reinforcing plate 1, for example, a nickel layer 3 is formed by plating. Then, the photo resist film 2' on the other side is removed. An etch resist 4 is spread on the surface of the deposited nickel layer 3 and the entire surface on the other side excluding the opening part area, and the reinforcing plate 1 is etched to form an opening part 5. By removing the etch resist 4 and photo resist 2, a nozzle part 6 is formed, and this nozzle part 6 and the surface of the reinforcing plate 1 is deposited with corrosion resistant and wear resistant metal, for instance, a nickel layer 7 by plating or the like.
