PROBLEM TO BE SOLVED: To manufacture a gas adsorbing device capable of suppressing the determine of a gas adsorbing material, and preventing any through-hole from being formed in a container. SOLUTION: After a gas adsorbing material 14 is filled in a gas hardly-permeable container 7 from an opening 8 of the gas hardly-permeable container 7 composed of a cylindrical metal member with one end opened, and the other end sealed, a lid material 11 having a substantially projecting longitudinal section composed of a bar-like part 12 with its outside diameter smaller than the inside diameter of the opening 8 and a flange 13 with its outside diameter larger than the inside diameter of the opening 8 is mounted to the gas hardly-permeable container 7 so that the bar-like part 12 is accommodated in the opening 8. An annular brazing filler metal 5 is installed close to a gap between an open end of the gas hardly-permeable container 7 and the flange 13 with the flange 13 side downwardly in the direction of gravity. The brazing filler metal 5 and its peripheral part are heated. After the brazing filler metal 5 is melted, and the brazing filler metal flows into a space between the gas hardly-permeable container 7 and the bar-like part 12 of the lid material 11 due to a capillary phenomenon, the brazing filler metal is cooled and solidified to seal the opening 8 of the gas hardly-permeable container 7.
