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.
