Manufacturing method of press-formed article, press-formed article, and press forming apparatus

A press forming apparatus manufacturing a press-formed article by press forming a bent-shaped portion to be pressed that is formed on a plate-shaped member to be pressed, comprising:

• a first die that includes a first press forming surface;
• a second die that includes a second press forming surface opposing the first press forming surface and forms a press space between the first die and the second die in which the portion to be pressed is stored, where the second press forming surface is provided with at least two groove-shaped holding portions, so as to be separated from each other by a predetermined distance;
• and
• a driving section that moves the first die and the second die relative to each other so as to approach each other, thereby decreasing the press space,
• wherein two first bent portions each protruding toward the second die and a second bent portion protruding towards the first die between the two first bent portions are formed on the portion to be pressed when the first die and the second die are driven by the driving section to move toward each other, and
• wherein the first die includes a pressing portion that is positioned between the two groove-shaped holding portions, has a shape protruding toward the second die, and presses the second bent portion on the portion to be pressed.
