According to an aspect of the present invention, a method for producing an oxide-dispersed strengthened alloy using organic-inorganic kneaded composition is provided. The method, comprises: a feedstock preparing step of preparing the organic-inorganic kneaded composition prepared by kneading, pulverizing and granulating ODS mixed powders and a polymer binder; a molding step of forming a semi-finished product having a predetermined shape using the organic-inorganic kneaded composition; a debinding step of removing the polymeric binder from the semi-finished product molded in the molding step; and a sintering step of extracting a final product having a predetermined shape by sintering and cooling the semi-finished product in which the polymeric binder has been removed in the debinding step.
