A bumper beam formed of an automobile fiber-reinforced resin member integrally includes a main body part that has a squared U-shaped cross section opening in one direction and that has a bottom wall and a pair of side walls, and a rib that connects the bottom wall and the pair of side walls. The main body part reinforced with continuous fibers and the rib reinforced with a discontinuous fiber are press formed at the same time to prevent the cross section from collapsing by reinforcing the main body part having a squared U-shaped cross section. It is possible to use the discontinuous fiber to reinforce the rib, which is difficult to reinforce with the continuous fibers, while ensuring high strength by reinforcing the main body part with the continuous fibers, and to eliminate the necessity of separately molding and joining the main body part and the rib.
