A crash energy absorption part 1 for an automobile according to the present invention is provided in a front portion or a rear portion of an automotive body, and absorbs crash energy when a crash load is input from a front or a rear of the automotive body. The crash energy absorption part 1 includes a top portion 5a, a tubular member 3 including a side wall portion 5c continuous to the top portion 5a via a shoulder part of a punch 5b, and a resin 9 applied or patched to at least an inner surface of the shoulder part of a punch 5b of the tubular member 3. The resin 9 has a thickness gradually changing in an axial direction from one end side toward the other end side. A thickest portion of the thickness is 8 mm or less and the resin is bonded to the inner surface with an adhesive strength of 10 MPa or more and is axially crushed when the crash load is input.
