An impact absorber includes an energy absorbing member that is formed of a composite material and absorbs impact energy by crushing in a predetermined crush direction, an outer tube member surrounding the periphery of the energy absorbing member over the energy absorbing member along the crush direction to prevent foreign objects from entering or impacting the energy absorbing member, and a pressing member in contact with the front end of the energy absorbing member and the front end of the outer tube member to press the energy absorbing member and the outer tube member simultaneously in the crush direction to thereby crush them. The outer tube member formed in a shape in which tubular portions are coupled in the crush direction, and is crushed in the crush direction while the tubular portions are regularly folded when the outer tube member is pressed by the pressing member in the crush direction.
