A forming method of overlapping and forming a laminated body made of a plurality of laminated fiber sheets on a shaping die, wherein the shaping die has a shaping die reference surface curved or bent relative to a predetermined direction and a shaping die bend surface intersecting the shaping die reference surface along the predetermined direction, wherein the laminated body has a laminated body reference surface curved or bent relative to the predetermined direction and a laminated body bend surface intersecting the laminated body reference surface along the predetermined direction, and wherein an angle at a concave side between the laminated body reference surface and the laminated body bend surface is larger than an angle at a concave side between the shaping die reference surface and the shaping die bend surface, the forming method comprising: overlapping the laminated body reference surface on the shaping die reference surface; and bending the laminated body bend surface toward the shaping die bend surface, wherein when a ridge where the shaping die reference surface and the shaping die bend surface intersect with each other is defined as a shaping die edge and when a ridge where the laminated body reference surface and the laminated body bend surface intersect with each other is defined as a laminated body edge, the laminated body edge is displaced from the shaping die edge on the shaping die reference surface, after the step of overlapping the laminated body reference surface on the shaping die reference surface and before the step of bending the laminated body bend surface toward the shaping die bend surface, and wherein a bending line, which is formed on the laminated body after bending the laminated body bend surface toward the shaping die bend surface, is along the shaping die edge. wherein the shaping die has a shaping die reference surface curved or bent relative to a predetermined direction and a shaping die bend surface intersecting the shaping die reference surface along the predetermined direction, wherein the laminated body has a laminated body reference surface curved or bent relative to the predetermined direction and a laminated body bend surface intersecting the laminated body reference surface along the predetermined direction, and wherein an angle at a concave side between the laminated body reference surface and the laminated body bend surface is larger than an angle at a concave side between the shaping die reference surface and the shaping die bend surface, the forming method comprising: overlapping the laminated body reference surface on the shaping die reference surface; and bending the laminated body bend surface toward the shaping die bend surface, wherein when a ridge where the shaping die reference surface and the shaping die bend surface intersect with each other is defined as a shaping die edge and when a ridge where the laminated body reference surface and the laminated body bend surface intersect with each other is defined as a laminated body edge, the laminated body edge is displaced from the shaping die edge on the shaping die reference surface, after the step of overlapping the laminated body reference surface on the shaping die reference surface and before the step of bending the laminated body bend surface toward the shaping die bend surface, and wherein a bending line, which is formed on the laminated body after bending the laminated body bend surface toward the shaping die bend surface, is along the shaping die edge. overlapping the laminated body reference surface on the shaping die reference surface; and bending the laminated body bend surface toward the shaping die bend surface, wherein when a ridge where the shaping die reference surface and the shaping die bend surface intersect with each other is defined as a shaping die edge and when a ridge where the laminated body reference surface and the laminated body bend surface intersect with each other is defined as a laminated body edge, the laminated body edge is displaced from the shaping die edge on the shaping die reference surface, after the step of overlapping the laminated body reference surface on the shaping die reference surface and before the step of bending the laminated body bend surface toward the shaping die bend surface, and wherein a bending line, which is formed on the laminated body after bending the laminated body bend surface toward the shaping die bend surface, is along the shaping die edge.
