Abstract: Disclosed is an ink jet print head and a method of producing the same, the ink jet print head including a plurality of ink ejecting orifices which are formed with a desired shape and a uniform size by only once using metal plating technique, having an excellent productivity and a low manufacturing cost. According to a first embodiment of the present invention, in the steps for forming an improved metal barrier layer, which is comprised of the conventional barrier layer and the conventional nozzle plate combined together, the metal barrier layer can be formed on a wetting layer by using electrolytic plating or electroless plating of Ni. As a result, an upper surface of a first photoresist mold is completely covered with the overflowing Ni. Further, an upper portion of a second photoresist mold is partially covered with the overplating Ni and is partially opened at a proper size and a desired shape. Thereby, an ink ejecting orifice is created at the upper portion of the second photoresist mold.
