A method, which is capable of manufacturing an ink jet recording head with a high degree of accuracy even though the density of an ink passage pattern is increased, includes the steps of forming an ink passage pattern on a substrate formed therein with an ink discharge pressure generating element from dissoluble resin; depositing an organic material on the substrate formed thereon with the ink passage pattern from the dissoluble resin by a vapor growth process at a temperature at which the dissolubility of the dissoluble resin is not lost, so as to form a coated resin layer; forming an ink discharge port in the coated resin layer in parts located above the ink discharge pressure generating element; and eluting the dissoluble resin.
