An impact-absorbing member characterized by being produced by arranging a molded article (D1) and a molded article (D2) in such a manner that the molded articles are superposed on each other, wherein the molded article (D1) is produced by molding a fiber-reinforced resin composition comprising a polyamide resin, a rubbery polymer having a reactive functional group and a fibrous inorganic filler and the molded article (D2) is produced by molding a non-reinforced resin composition comprising a polyamide resin and a rubbery polymer having a reactive functional group, and wherein the side of the impact-absorbing member on which the molded article (D1) is arranged serves as a side which is to be subjected to impact force. An impact-absorbing member is provided, which can absorb an external impact energy with a smaller deformation amount. L'invention concerne un élément d'absorption des chocs caractérisé en ce qu'on le produit en agençant un article moulé (D1) et un article moulé (D2) de telle manière que les articles moulés sont superposés l'un sur l'autre, dans lequel on produit l'article moulé (D1) en moulant une composition de résine renforcée de fibres comprenant une résine polyamide, un polymère caoutchouteux ayant un groupe fonctionnel réactif et une charge inorganique fibreuse et on produit l'article moulé (D2) en moulant une composition de résine non renforcée comprenant une résine polyamide et un polymère caoutchouteux ayant un groupe fonctionnel réactif, et dans lequel le côté de l'élément d'absorption des chocs sur lequel l'article moulé (D1) est disposé sert de côté qui doit être soumis à la force d'impact. L'invention concerne un élément d'absorption des chocs, qui peut absorber l'énergie d'un choc externe avec une quantité inférieure de déformation.
