A method for reducing springback in a press-formed part according to the present invention includes an analytic model forming step including forming an analytic model of the part from plane elements and/or solid elements; a stressed-state setting step including setting each of the elements of the analytic model to a stressed state that causes a springback; a rigidity-contributable-portion detecting step including performing an optimization analysis for shape on the analytic model with the elements set to the stressed state in the stressed-state setting step to detect a portion of the part that highly contributes to the rigidity of the part; and a rigidity improving step including applying a rigidity improving means to the part on a basis of the portion detected in the rigidity-contributable-portion detecting step.
