PROBLEM TO BE SOLVED: To eliminate the insufficient collapse of a structure, and utilize the deformation stroke of the structure to the maximum extent in an energy absorbing member having the structure which can absorb impact energy by its deformation when impact is inputted. SOLUTION: Each structure 4 has a hollow truncated quadrangular pyramidal shape, and the thickness of the structure 4 is thinned on a corner between side walls 16. Therefore, by an impact load to the structure 4, first, the adjacent side walls 16 are torn off, and after that, each side wall 16 is independently buckled. Since the side walls 16 are buckled without being mutually overlapped, the insufficient collapse of the structure 4 may not occur, and the deformation stroke thereof is utilized to the maximum extent.
