Zusammenfassung:	PROBLEM TO BE SOLVED: To solve at least one of the conventional problems of a metallic evacuated double-walled container: such that it affects human bodies, the environment, and devices; it prevents the dissolution and reuse of inner and outer containers; and product yields are not enhanced because of low adhesiveness to stainless steel. SOLUTION: An exhaust port 4 through which a space between inner and outer containers 1 and 2 made of stainless steel is evacuated is sealed with glass sealing brazing filler material 5 which will not hinder the reuse of the inner and outer containers 1 and 2 dissolved at the same time, for example, a material which does not contain metals usually contained in conventional low-temperature melting glass sealing brazing filler material, such as lead, tin, and bismuth, but which contains a metal having a higher melting point that those metals, or a material containing a metal having a lower specific gravity than the molten components of stainless steel, or a material not containing components which pose problems on food hygiene.
