To compensate for a decrease in reaction force of a bumper reinforcement, which is made of an aluminum alloy extrusion having two end portions subjected to bend forming and crushed portions on the respective end portions, against an impact load in end impact involved in crushing, and compensate for a decrease in energy absorption amount of the bumper reinforcement. Assuming a space between two flanges includes a first region from a center line of the thickness between the flanges to an outer flange and a second region from the center line to an inner flange in a cross section of the crushed portion perpendicular to an extrusion direction, area of the webs located in one (for example, the first region) of the two regions is larger than area of the webs located in the other region (for example, the second region).
