PROBLEM TO BE SOLVED: To provide a method and device for simply and precisely predicting the shrinkage rate and warpage quantity of a molding in the injection molding process. SOLUTION: In order to analyze the warpage of the molding, the total warpage quantity is calculated on the basis of (1) a branching structure warpage quantity obtained from the angle between a base part and a branching body in a branching part, the wall-thicknessward average of an inward shrinkage rate in a branching part, etc., and (2) a bimetal warpage quantity obtained from the inward and wall-thicknessward distribution of the inward shrinkage rates of the base part and the branching part in the branching part.
