A crashworthiness energy absorption part 1 for automotive according to the present invention absorbs collision energy by undergoing axis crush deformation when a crashworthiness load is input from the front or back of the automotive body, includes: a tubular member 3 with a top portion 5a and a pair of side wall portions 5b; a closed cross section space forming wall part 9 provided to extend over the top portion 5a inside the tubular member 3, having both edge portions joined to inner surfaces of the pair of side wall portions 5b, and forming a closed cross section space between itself and a peripheral wall portion of the tubular member 3; and a resin 11 filling the closed cross section space and including a rubber-modified epoxy resin and a curing agent. The resin 11 has tensile breaking elongation of 80% or more, adhesive strength to the tubular member 3 and closed cross section space forming wall part 9 of 12 MPa or higher, and a compression nominal stress of 6 MPa or higher at a compression nominal strain of 10%.
