Abstract

Provided is a method for manufacturing a press molded product having superior shape fixability for a component having a top plate part and a flange part that are curved along the longitudinal direction and a vertical wall part at the end part of the flange part in the longitudinal direction. When a metal plate is manufactured by press molding into a product shape having a top plate part (1) and flange part (2) continuous in the direction of width via a side wall part (3), the top plate part (1) and the flange part (2) curved so as to form a protrusion to the top plate part (1) side along the longitudinal direction, a pulled out part (5) with a dimension in the direction of width larger than the top plate part (1) continuous with the end of the top plate part (1) in the longitudinal direction, and a vertical wall part (6) continuous with the end of the flange part (2) in the longitudinal direction, rising on the top plate part (1) side, and having an upper edge continuous with the pulled out part (5), the metal plate is press molded into the targeted product shape after preliminary molding into a shape wherein the line length of a continuous part for the end part of the flange part (2) in the longitudinal direction and the vertical wall part (6) is shorter than the line length in the product shape.
