[Object] To make it possible to make impact absorption at the time of a collision even when there is no sufficient space. [Solution] An impact absorption member according to the present invention includes: a member that is placed adjacent to an exterior material 110 of an automobile and in which a height in a direction orthogonal to the exterior material is larger than a width in a direction along the exterior material in a cross section orthogonal to an extending direction of the member. By this configuration, a first member 122 and a second member 124 are arranged so as to extend in different directions and be adjacent to the exterior material 110 of an automobile, and therefore impact absorption at the time of a collision can be made even when there is no sufficient space.
