Abstract
A material is press formed into a component shape including a top sheet portion including a curved outer peripheral edge portion curved in such a manner as to be recessed inward, a vertical wall portion, and a flange portion. When a lower die and a pad sandwich a sandwiching region that is a region including at least a part of a region corresponding to the top sheet portion, an upper die is moved in a pressing direction to perform bending while moving the sandwiched material to the vertical wall portion side. A surface of the lower die that sandwiches the sandwiching region is provided with one or more ridgelines for forming bends. The ridgelines are set at positions such that, when the bending is complete, the position of the top sheet portion is located on the vertical wall portion side rather than the positions of the ridgelines.
