PROBLEM TO BE SOLVED: To provide a gas adsorption device facilitating confirmation of a decompression sealed state.SOLUTION: A gas adsorption device 5 includes: a gas adsorption substance 9 that comprises at least copper-ion-exchanged ZSM-5 type zeolite and adsorbs nitrogen; an aluminum storage container 11 that seals both sides of a storage part 10 that stores the elongated, flat and cylindrical gas adsorption substance 9 in a decompression state; and a tight contact part 13 where opposed inner surfaces of the facing storage container 11 make tight cantact each other, between a sealing part 12 of a side where a narrow part 14 of the storage container 11 is sealed with a sealing glass and the storage part 10. By sound generated when impact is applied to the gas adsorption device 5, a decompression sealed state can be easily confirmed. |
