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.
1. A thermal insulator comprising at least a core material and a gas adsorption device capable of adsorbing a gas, as well as an outer covering material having a gas barrier property and covering the core material and the gas adsorption device, wherein a pressure of an inside of the outer covering material is reduced,the gas adsorption device comprises: a layer of copper ion-exchanged ZSM-5 type zeolite,a layer of moisture adsorption material, anda structure in which the copper ion-exchanged ZSM-5 type zeolite and moisture adsorption material are held, c...
