PROBLEM TO BE SOLVED: To provide an energy absorbing member 10 high in the weight efficiency of energy absorption. SOLUTION: The energy absorbing member 10 comprises a cylindrical body 11 having a peripheral wall; and a plurality of line-shaped high deformation resisting portions 12 provided on the peripheral wall in a circumferential direction at even intervals, and having higher deformation resistance than those of other parts constituting the peripheral wall. Each line-shaped high deformation resisting portion 12 extends from one end to the other end in the body so as to meander in a wave shape in a cylinder axial direction. When a compressing load in the cylinder axial direction is inputted into the body 11, parts between the line-shaped high deformation resisting portions 12 are individually deformed into bellows shapes.
