PROBLEM TO BE SOLVED: To create a metal mold CAD model by reflecting information about a metal plate that is subjected to press molding. SOLUTION: A FEM (finite element method) mesh model creating part 14 creates a mesh model showing elements and nodes of a finite element method, which correspond to the plane of a metal mold CAD model with reference to movement instruction points on the plane of the metal mold CAD model. A dynamic deformation solver part 15 deforms the mesh model on the basis of a motion vector at the movement instruction point and information about material with which a metal mold created by the metal mold CAD model performs press molding. A CAD model deforming part 16 deforms a base bottom surface constituting the metal mold CAD model on the basis of the nodes of the mesh model and displacement of the nodes between undeformed mesh model and deformed mesh model to create a deformed metal mold CAD model.
