A cushioning body of a cask, stably exhibiting impact absorption performance. The cushioning body (6) is constructed such that the directions of fibers are combined so as to be parallel to the direction of an input of impact and receives impact in the direction parallel to an end surface (1tp) of the cask. Further, the cushioning body (6) includes a first impact absorption body (B1) made from a first material, second to fourth impact absorption bodies (B2-B4) made from a second material that has lower compression strength than the first material and absorbs impact in the direction orthogonal to the end surface (1tp) of the cask, and fifth to eighth shock absorption bodies (B5-B8) made from a third material that has lower compression strength than the second material and absorbs impact in the direction orthogonal to the end surface (1tp) of the cask. Holes are provided in at least the first shock absorption body (B1).
