Abstract
A manufacturing method of press-formed article according to the present invention includes a step of placing a flat plate member between a first die and a second die, and a step of causing a first press portion and a second press portion approach each other, thereby pressing the flat plate member. In the step of placing, the flat plate member is placed so that a first main surface and a second main surface align with a vertical direction. In the step of pressing, the flat plate member is vertically pressed by causing the first press portion and the second press portion to approach each other in the vertical direction, and a thick portion is formed on the flat plate member by causing a part of a material of the flat plate member in the vertical direction to flow into a thickened portion-forming section formed on a first opposing surface.
