The present invention provides a method for manufacturing a press-molded article, the method comprising inserting a blank (200) between a die (20) and a blank holder (30) and pressing the blank (200) in a press direction (P) by means of a punch (10). When viewed from the press direction (P), an edge (24) of the die (20) includes a curved part (241) and an edge (201) of the blank (200) includes a curved part (211). The interval (w) between the blank edge curved part (211) and the edge (24) of the die (20) differs between one end portion (211a) and the other end portion (211b) of the blank edge curved part (211). The blank holder (30) holds a portion of the edge (201) of the blank (200) together with the die (20). The interval (d) between an edge (34) of the blank holder (30) and the edge (201) of the blank (200) held between the blank holder (30) and the die (20) changes along the edge (201) of the blank (200). The interval (d) is the largest at the blank edge curved part (211).
