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.
