PURPOSE: An ink jet recording head and a method for manufacturing the same are provided to obtain a high-density, high-accuracy ink jet recording head which is capable of improving a frequency response while maintaining proper discharge performance. CONSTITUTION: A method for manufacturing an ink jet recording head utilizing ink bubbling by heating of an exothermic resistor to thereby eject ink includes the steps of preparing a substrate provided with the exothermic resistor, applying such first resin on the substrate as to provide a first mold shape for forming the nozzle channel and the 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. |
