PROBLEM TO BE SOLVED: To provide a method for manufacturing an ink jet recording head by which a movable member is formed in a nozzle channel between an ink inlet and an outlet to thereby provide a high-density, high-accuracy, and high- reliability ink recording head which can improve a frequency response while maintaining proper discharge performance, and to provide the ink recoding head.;SOLUTION: The method for manufacturing the ink jet recording head utilizing ink bubbling by heating of a heating resistor to thereby eject ink includes the steps of: preparing a substrate provided with the resistor; applying such first resin on the substrate as to provide a first mold shape for forming the nozzle channel and movable member; forming the first mold shape using the first resin; applying, on the substrate, second resin over the first mold shape for forming the nozzle channel and the movable member; and removing the first mold shape.;COPYRIGHT: (C)2003,JPO
