SEALED CONTAINER, THERMAL INSULATOR, AND GAS ADSORPTION DEVICE

摘要

A sealed container (1) includes at least an outer container (2) and a gas adsorption device (4) being provided in a sealed space (3) within the outer container (2) and being capable of adsorbing a gas. The gas adsorption device (4) includes at least a copper ion-exchanged ZSM-5 type zeolite and a primary material having a lower gas barrier property than the outer container (2) does.
