Zusammenfassung:	An object is to suppress falling or rising of an end of a press-formed product and twisting of the press-formed product due to springback so as to suppress a shape defect of the press-formed product due to the springback, and, in designing a shape of a press-formed product produced by press-forming a sheet material, a curvature radius (R1) of a concave curved portion and a curvature radius (R2) of a convex curved portion of a concave and convex curved shape of an additional shape arranged on the press-formed product where the concave curved portion and the convex curved portion are continuous are set to be the same.
