To provide a cask in which shock-absorbing characteristics hardly change.SOLUTION: A cask comprises: a transport container for housing housed objects; and a buffer that includes a porous body and is mounted on the transport container. The porous body contains a synthetic resin. When it is defined that an energy absorption characteristic value is equal to an average compressive stress[MPa]×a crushing rate[%]/100, the energy absorption characteristic value is 0.42 or more.SELECTED DRAWING: Figure 1 【課題】衝撃吸収特性が変化しにくいキャスクを提供する。【解決手段】キャスクは、被収容物を収容する輸送容器と、多孔体を含み、輸送容器に装着されている緩衝体と、を備え、多孔体が、合成樹脂を含み、エネルギー吸収特性値＝平均圧縮応力［ＭＰａ］×圧潰率［％］／１００と定義したときに、エネルギー吸収特性値が０．４２以上である。【選択図】図１
