Abstract
A center pillar reinforcement is produced satisfactorily by using a high-tensile material having a low ductility as a blank. The center pillar reinforcement is produced by performing a first step for producing a first intermediate formed product on which a body is partially formed by press-forming the blank using a first press-forming device for drawing, and a second step for pressing the first intermediate formed product by using a second press-forming device for bend-forming.
