Structural Member And Method For Manufacturing Same

Abstract: This manufacturing method for a structural member (10) comprises: a step for preparing a raw material (M); and a forming step for using a die (20) to perform cold press work on the raw material (M). The die (20) includes a pad (23), an upper die (22), and a lower die (21). The lower die (21) includes first and second lower dies (211, 212). The forming step includes first and second steps. In the first step, while a side surface (212c) of the second lower die (212) is retreated with respect to a side surface (211c) of the first lower die (211) when viewed in the pressing direction, the raw material (M) is pressed with the pad (23) and the first lower die (211). In the second step, the raw material (M) is sandwiched by the upper die (22) and the first lower die (211), and the raw material (M) is sandwiched by the upper die (22) and the second lower die (212) by moving the second lower die (212) so that the side surface (212c) is aligned with the side surface (211c).
