To provide an impact absorption member that can improve the collision energy absorption performance while suppressing an influence on rigidity of the entire vehicle body.SOLUTION: An impact absorption member (100) includes a structural member (10) and a reinforcement member (30). The structural member (10) includes vertical walls (11, 12), a top plate (13), and ridge line portions (14, 15). The reinforcement member (30) includes vertical walls (31, 32), a top plate (33), and ridge line portions (34, 35). The vertical walls (31, 32) are disposed along the vertical walls (11, 12) inside the structural member (10). The top plate (33) is located opposed to the top place (13) inside the structural member (10). The reinforcement member (30) is bonded to the structural member (10). The ridge line portions (34, 35) respectively include recessed portions (341, 351). The recessed portions (341, 351) are disposed at positions opposed to each other. The recessed portions (341, 351) extend to the middle of the vertical walls (31, 32) and the top plate (33).SELECTED DRAWING: Figure 1
