PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas cell in which transpiration of the sealed metal is suppressed.SOLUTION: A method of manufacturing a gas cell includes: a step for preparing metal, a base substrate having a bottomed hole opened to a first surface and a substrate for sealing; a step for overlapping the sealing substrate on the first substrate so as to enclose the metal in a hole; a first joining step for having a sealing region surrounding an opening and a joining region surrounding the sealing region and heating and joining the base substrate and the sealing substrate in the joining region; and a second joining step for heating and joining the base substrate and the sealing substrate in the sealing region and sealing the hole.
