A method for manufacturing a press molded product includes forming a plurality of corner portions in a pressed portion of a pressed member, providing the pressed member between a first die and a second die, and press molding the pressed portion to decrease a height of the pressed portion. The press molding includes forming a pair of first bent portions in the pressed portion by means of the corner portions, the pair of first bent portions being bent to protrude toward the second die, forming a second bent portion in the pressed portion by means of the corner portions while holding the pair of first bent portions by a pair of holding portions, the second bent portion being bent to protrude toward the first die from a position between the pair of first bent portions, and pressing and deforming the second bent portion.
