Abstract: The present invention reduces the gap generated between a first metal plate member and a second metal plate member in monolithic molding with the two metal plate members in an overlapped state. A method for manufacturing a press-molded article according to the present invention is characterized by performing press-molding using a punch 41 having a raised portion 42 on which a first metal plate member PL1 and a second metal plate member PL2 are positioned and fixed in an overlapped state, a die 31 having a recessed portion 31a into which the raised portion 42 of the punch 41 is to be inserted, and a pad 32 that applies a prescribed load to the first metal plate member PL1 and the second metal plate member PL2 when the raised portion 42 of the punch 41 is inserted into the recessed portion 31a of the die 31, wherein the load applied to the first metal plate member PL1 and the second metal plate member PL2 by the pad 32 is smaller than the load required to prevent uplift from the punch 41 in a top plate portion.
