Claim:
1. A method of analyzing a deformation state of a resin molded article, comprising: dividing the resin molded article into micro regions; and optimizing an objective function using a topology optimization method under a prescribed constraint condition and a prescribed restraint condition, wherein the prescribed constraint condition is a trend of amounts of deformation of the resin molded article, the prescribed restraint condition is a contribution rate expressing an extent to which deformation of each micro region contributes to deformation of the resin molded article, the contribution rate is (1−(volume which satisfies the restraint condition and can be deleted/volume of an original shape)×100(%)), and the optimization of the objective function optimization is performed so as to minimize reduction in rigidity of the resin molded article.
