PROBLEM TO BE SOLVED: To provide a double structure pipe for cryogenic fluid and a double structure storage tank for cryogenic fluid capable of transporting or storing cryogenic fluid, with a simple structure and at low cost.SOLUTION: A double structure pipe 1 for cryogenic fluid includes an inner pipe 2, and an outer pipe 3 externally fitted to the inner pipe 2 with a sealed cylindrical space; flows cryogenic fluid to the inside of the inner pipe 2; charges inactive gas having a melting point and a boiling point equal to or more than a temperature of cryogenic fluid, in the cylindrical space between the inner pipe 2 and the outer pipe 3; liquefies or solidifies inactive gas by cryogenic fluid flowing inside the inner pipe 2; forms at least one of a liquefied inactive gas layer and a solidified inactive gas layer on the outer peripheral surface of the inner pipe 2; and thereby forms a pseudo vacuum layer 5 close to vacuum in the cylindrical space.SELECTED DRAWING: Figure 1
