PURPOSE:To make a coolant compression pump and the like unnecessary and to simplify the superconductive wiring line by furnishing a superconductive wire in a coolant transferring tube which links a coolant container and superconductive appliances. CONSTITUTION:A coolant transferring tube 2 is composed into a double tube of an armoring tube 4 and a coolant jar 5 to be an inner tube, and the coolant jar 5 is held concetric to the armoring tube 4 by supports 7 through a vacuum adiabatic layer between the jar 5 and the tube 4. Inside the coolant jar 5, liquid nitrogen (h) pumped from a cold evaporator 1 is filled, and moreover, plural superconductive wires 8 are arranged in the condition surrounded by the liquid nitrogen (h). The superconductive wires 8 have a composition shown as the formula Aa Bb Cc, where A is one element selected from Ia, IIa, and IIIa families in the periodic table, B is one element selected from Ib, IIb, and IIIb families, and C is oxygen or fluorine.
