PROBLEM TO BE SOLVED: To improve the pressure resistance and airtightness of a brazing layer of a container formed of a plurality of container components brazed together. SOLUTION: The container 10 is composed of a first container component 14 and the second container component 12 which are so arranged that openings of the container components 14, 12 are opposite to each other. The opening 44 of the first container component 14 is provided with a first flange 18, and the opening 42 of the second container component 12 is provided with a second flange 16. Between both flanges 18, 16, a first gap 24, a second gap 28, and a third gap 26 are formed in increasing order from the inner periphery side. The second gap 28 is formed to be greater than the first gap 24 and smaller than the third gap 26. When a brazing material 36 placed in the second gap 28 is heated to melt, the brazing material spreads first into the narrowest first gap 24, and spreads sufficiently over the inner edge of the first gap 24, that is, speards through to the openings 42, 44. As a result, the brazing material is spread over the inner edges beteen both flanges 18 and 16, which improves the pressure resistance of the brazing layer. COPYRIGHT: (C)2007,JPO&INPIT
