PROBLEM TO BE SOLVED: To exhibit always stabilized shock absorbing ability without dispersion in energy absorbing characteristics. SOLUTION: This energy absorbing member has a structure 4 formed into a hollow truncated pyramid, and absorbs impact energy by deforming the side wall 16 of the structure 4 when impact is inputted. The side wall 16 has a polygonal line in a part in the vicinity of a base against the line of action (X-X) of a load, and when the impact is inputted, the side wall 16 generates initial deformation always in an outside direction. The side wall 16 is deformed in an always constant pattern when the impact is inputted, and at this time, ideal load absorbing characteristic is shown, therefore, always stabilized energy absorbing ability is exercised.
