ABSTRACT:
A nozzle plate is manufactured by providing a material plate and a punch. The material plate is punched by the punch to form a provisional nozzle orifice hole on the material plate. The punching is repeated such that the provisional holes formed by a given punch are arranged in line. A bulged portion which is bulged on a back side of the material plate is removed to form the completed nozzle orifice.
