<P>PROBLEM TO BE SOLVED: To provide a gas adsorption device that can be sealed by simple condition management. <P>SOLUTION: A bottomed cylindrical metal container 11, to which a cylindrical narrow part forming part 15 is bonded on an opening side of a bottomed cylindrical storage part 14 of gas adsorption material by a method such as eutectic bonding, is used. The storage part 14 of gas adsorption material is filled with a gas adsorption material 13 activated by heating from the opening 12 of the bottomed cylindrical metal container 11. After that, a narrow part 16, where inner surfaces of the cylindrical narrow part forming part 15 positioned near the opening 12 are closed with each other, is arranged to decompress the inner part of the metal container 11 and a space around the metal container 11 in a vacuum heating furnace. In addition, the narrow part 16 is heated so that the metal constituting the narrow part forming part 15, where the narrow part 16 is arranged, is melted to close a gap of the narrow part 16. Then, the device is manufactured by a method of sealing the gap of the narrow part 16 by cooling solidification. A metal whose melting point is lower than that of the metal constituting the storage part 14 of gas adsorption material is used for the metal constituting the narrow part forming part 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
