On a front surface 15 a of a bumper beam 15 covered by a bumper cover 13, an impact energy absorber 1 is fixed by clips 19. The impact energy absorber 1 is formed into a cylindrical shape by lapping a film-shaped paper band material and an aluminum band material on each other and winding the band materials spirally, and the wall portion thereof is formed with concave and convex portions arranged in a spiral form or a ring form. When a pedestrian collides with the bumper cover 13, and the cover 13 is deformed and the impact energy absorber 1 is subjected to a load, the impact energy absorber 1 is plastically deformed to absorb impact energy, by which the safety of pedestrian is ensured.
