ABSTRACT:
A method of manufacturing an ink jet recording head, having the steps of forming an ink flow path pattern on a substrate with the use of a dissoluble resin, the substrate having ink ejection pressure generating elements thereon, forming on the ink flow path pattern a coating resin layer, which will serve as ink flow path walls, by dissolving in a solvent a coating resin containing an epoxy resin which is solid at ordinary temperatures, and then solvent-coating the solution on the ink flow path pattern, forming ink ejection outlets in the coating resin layer above the ink ejection pressure generating elements, and dissolving the ink flow path pattern.
