A resin impact absorber comprising a hollow columnar body or a cylindrical hollow columnar body made of a resin having a bending modulus of 500 to 5,000 kgf/cm<3>, and having a honeycomb section, wherein a reaction to compression ratio curve at the time of compression in a longitudinal direction of the columnar body satisfies (a) yield strength >/= 100 Tf/m<2> and (b) compression energy absorption quantity >/= 50 TF m/m<3>. The resin impact absorber is compact in size and light in weight and exhibits a high impact energy absorption capacity. The place or structure in which the impact absorber is installed can escape from remarkable damage and destruction when is receives a high impact force.
