Abstract

A method for manufacturing a press-formed article () includes a first step for forming a base sheet portion, a first rising portion, and a first strip portion from a sheet-shaped workpiece having a first edge portion and a second edge portion; and a second step for forming a second rising portion by causing a strip-shaped first zone including the second edge portion to be disposed between a first upper die and a first lower die from both sides, causing a second zone adjacent to the first zone to be disposed between a second upper die and a second lower die from both sides, and moving the first upper die and the first lower die relative to the second upper die and the second lower die, wherein, in the second step, a part of the second rising portion which is connected to a vertical ridge line () is shear-deformed.
