According to the present invention, in a cryogenic liquid transfer tube, a conduit through which a cryogenic liquid is transferred is insulated by using a plurality of heat insulating films having a multi-layered film structure so that each film layer is spaced apart by a step- The plurality of heat insulating films are arranged so as to be surrounded by a plurality of inward and outward folds around the conduit while the inner heat insulating film and the outer heat insulating film are arranged so as to intersect with each other, Extend it as much as possible to make more efficient insulation possible.
