To absorb energy so that a reaction force against a pedestrian does not increase to a level higher than or equal to a certain level at a time of collision, a bumper absorber (20) includes: a first structure (21) whose cross-sectional structure perpendicular to a Y direction has a mountain shape; and a second structure (22) which has a shape such that the second structure is simply compressed in an X direction. The first structure (21) has, in a rear end surface (21b) thereof, a groove (21c) extending in the Y direction. A dimension (A) of the first structure (21) in the X direction is greater than a dimension (A') of the second structure (22) in the X direction. Densities of the first and second structures (21 and 22) and a width (D) and a depth (C) of the groove (22c) of the first structure (21) are set to specific ranges.
