[Object] In forming a press-formed product (10) that is made of a high-tensile steel sheet having a tensile strength of 390 MPa or more, and has a substantially gutter-shaped cross section and an outward continuous flange (16), wrinkling in ridges (12a, 12b) and cracking in the outward continuous flange are reduced. [Solution] A method for manufacturing a press-formed product (10) that is made of a high-tensile steel sheet of 390 MPa or more, and has a substantially gutter-shaped cross section and an outward continuous flange (16) in at least one end in a predetermined direction includes a first step in which, after a first pad (34-1) restrains at least a part of a portion to be formed into a gutter bottom (11) in a forming material (33), a second pad (34-2) restrains at least a part of the end of portions to be formed into ridges (12a, 12b) and subsequently carries out press forming.
