An automotive crashworthiness energy absorptive part absorbs crashworthiness energy by crushing axially when a crashworthiness load is input from a front side or a rear side of an automotive body, and includes: a tubular member formed of a steel sheet with a tensile strength of 590 MPa to 1180 MPa, the tubular member including a top portion and a pair of side wall portions continuous from both ends of the top portion via corner portions; a closed cross section space forming wall member formed of a steel sheet with a tensile strength lower than the tubular member, the closed cross section space forming wall member being disposed on an inner surface side of the tubular member and forming a closed cross section space between the closed cross section space forming wall member and at least the corner portion; and a resin provided in the closed cross section space.
