In order to improve strength and rigidity without increasing sheet thickness, a method is provided for easily forming a rib as a reinforcing material in press-moldings and a press-molding with a reinforcing rib. This method for manufacturing press-moldings with a reinforcing rib is characterized by the following: comprises a press-molding process for simultaneously press-molding a reinforcing rib and a thermoplastic base material sheet that are each disposed in the press-molding die; the reinforcing rib being obtained by a thermoplastic rib base material and a fiber sheet material in which multiple fibers have been accumulated and bonded, both being stacked and integrally molded so as to have a main reinforcing rib portion and a bonding portion for bonding to the thermoplastic base material sheet; the fiber sheet material having voids between the fibers; and some of the heat-softened thermoplastic base material sheet entering the voids of the fiber sheet material located in the bonding portion during the press-molding process and being fixed.
