<P>PROBLEM TO BE SOLVED: To provide a vacuum triple metal vessel which is manufactured in a short period of time. Ž<P>SOLUTION: In the vacuum triple metal vessel 20 where an inner vessel 23, an inner vessel 25, and an outer vessel 27 are soldered at mouth parts 11, 14, and 15 placed in the respective vessels 23, 25, and 27 and vacuum insulation is performed between the inner vessel 23 and the outer vessel 27, the middle vessel 25 has an inner vessel body 13 which is elastically deformed by external force and is in contact with the inner vessel 23 or the outer vessel 27, and the outer vessel 27 has an outer vessel lid body 19 which is soldered to an outer vessel body 12 and elastically deformed when receiving external force to push the inner vessel body 13. Thus, when the inner vessel body 13 is brought into contact with the inner peripheral surface of the outer vessel body 12 and the outer vessel body 12 is cooled down, heat of the inner vessel body 13 moves to the outer vessel body 12 via a contact part. The inner vessel body 13 is speedily cooled down together with the outer vessel body 12. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
