Abstract

The present invention addresses the problem of suppressing torsion of a press-molded article and falling off or jumping up of an end portion of the press-molded article caused by springback so as to suppress deterioration in shape of the press-molded article caused by springback. The present invention is characterized in that, when design is performed for the shape of a press-molded article obtained by press molding of a sheet-like material, the radius of curvature (R1) of a recessed curve section and the radius of curvature (R2) of a projected curve section are made equal to each other in a projected/recessed curve shape in which the recessed curve section and the projected curve section are contiguous with each other, the recessed curve section and the projected curve section belonging to an additional shape disposed in the press-molded article.
