The present disclosure relates to a bumper back beam to be disposed inside a bumper cover, for reducing impact from outside the bumper cover. The bumper back beam includes a body including a synthetic resin, and a fiber composite reinforcing material including a hollow section. The fiber composite reinforcing material is fastened inside the body. The bumper back beam has high reliability, by having excellent ability to absorb impact energy because cracks almost do not occur during collision since it not only provides satisfactory strength and stiffness but also has high elongation with synthetic resin and fiber composite reinforcing materials generating synergies, and especially by having excellent impact resistance since fiber composite reinforcing materials take the shape of a hollow section.
