An automobile bumper beam to be disposed in a vehicle width direction includes: a small sectional area portion at a center in the vehicle width direction; paired sectional area changing portions continuous to outsides in the vehicle width direction of the small sectional area portion; and paired large sectional area portions continuous to outsides in the vehicle width direction of the sectional area changing portions. The small sectional area portion projects most outward in a front-rear direction at paired impact load input portions. Thus, impact load in minor collision is inputted as two-point concentrated load to the paired input portions of a bumper beam body, reducing a peak value of bending moment acting on the body, and the sectional area changing portions and large sectional area portions bear the moment, thereby enhancing strength of the body, reducing its thickness and weight, and achieving an excellent collision energy absorbing effect.
