摘要： The present invention provides an ink jet recording head forming method which can be improved in a discharging characteristic. The method includes at least the step of forming an ink flow path pattern on a substrate by a photodecomposable positive type resist resin, the step of once executing each of the steps of applying, exposing and baking thereon a nozzle-constituting resin layer which is a negative type resist containing an optical cation polymerization starting agent and having an epoxy resin as a chief component with respect to each of an ink flow path pattern and an ink discharge port pattern, the step of collectively developing unexposed portions on the respective nozzle-constituting resin layers, and the step of removing the formed photodecomposable resin. Therefore, a minute projection is formed at a location separate from the substrate surface side of the cross section of the ink discharge port and thus, the deviation of the flying direction of an ink droplet due to the asymmetry of the inner shape of the ink flow path is minimized.
