ABSTRACT:
The present invention provides a method for manufacturing an ink jet recording head utilizing ink bubbling by heating of an exothermic resistor to thereby eject ink and a method manufacturing the same, including 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. By this method, the movable member is formed in the nozzle channel between the ink inlet and the exothermic resistor to thereby provide a high-density, high-accuracy ink jet recording head which can improve a frequency response while maintaining proper discharge performance.
