A bumper back beam for a vehicle includes an impact part positioned in a center portion, and tower parts formed at rear portions of both sides of the impact part so as to be fixed to crush boxes on the front ends of side members of a vehicle body, and is characterized in that the impact part is formed such that the section of the impact part has an inner space which is open towards the opposite inside portions of a bumper, and a stiffener is received in the inner space, wherein the inner space and the stiffener are formed with a curvature which is smaller than that of the back beam such that clearances are formed at both sides between the inner space and the stiffener. The bumper back beam improves impact resistance and maintains appropriate deformation while preventing damage to the side members, when a bumper is impacted.
