A bumper absorber (2) includes an upper leg (2b) and a lower leg (2c), each of which extends in a longitudinal direction of an automobile, and a spanning portion (2d). The spanning portion (2d) connects the upper leg (2b) and the lower leg (2c), and faces an outer surface side of the bumper absorber (2) in a longitudinal direction of the automobile. Each of the upper leg (2b) and the lower leg (2c) includes a buckling inductive portion (2f) that serves as a starting point of the buckling that is caused when the spanning portion (2d) receives an impact load. The buckling inductive portion (2f) is formed as an angular transition portion in which the angle of inclination between inner side surfaces changes. The inner side surfaces mutually face between the upper leg (2b) and the lower leg (2c) that include the buckling inductive portion (2f).
