Abstract

Provided is a method for manufacturing a press molded product that can greatly reduce spring-back in a side view, that is, camber-back and material strength sensitivity of camber-back without requiring complex mold designs even when high tensile steel is used. For manufacturing a metal plate 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) and having a hat-shaped cross-section wherein the top plate part (1) and the flange part (2) are curved convexly or concavely on the top plate part (1) side along the longitudinal direction, the method has a first step for manufacturing an intermediate component by press molding into a component shape having a hat-shaped cross-section with the curvature along the longitudinal direction of each of the top plate part (1) and the flange part (2) having a second radius of curvature smaller than the radius of curvature in the product shape, and a second step for press molding the intermediate component into the product shape.
