PROBLEM TO BE SOLVED: To dispense with the use of a constitutional element of a separate body such as a condensing tank by connecting a reserver opened to atmospheric air to a container capable of storing a liquid phase of a multicomponent low temperature mixture and guiding a conduit pipe making contact with the reserver so as to be thermally conducted from a head space region of the container. SOLUTION: A storage device 1 to store a multicomponent low temperature mixture as liquid 10 in a container 12 distributes the liquid 10 from the container 12 through a discharge conduit run 14, but a gaseous phase of the mixture is generated in a head space region 16 of the container 12 by thermal leakage to the inside of the container 12. A conductor 18 communicates the head space region 16 and its lower part, a reserver 20 a head part of which opens to atmospheric air carries out thermal transmission by surrounding a part of the conductor 18, and flow of the liquid phase constituted of the liquid phase is communicated to the container 12 so as to inflow in the inside of the reserver 20 by a conductor 22. As the reserver 20 opens to the atmospheric air, liquid 23 contained in the reserver 20 is furnished with concentration contributing to a component lower in volatility out of the multicomponent low temperature mixture to be stored.
