PROBLEM TO BE SOLVED: To provide a cryostat of a superconductive cable which is constituted to compensate a stress generated according to a temperature difference and to hold the other vacuum state even if either of the vacuum states is released by setting two vacuum conditions between the superconductive cable and a terminal end connection box. SOLUTION: This cryostat of the superconductive cable includes an inside metal tube in which liquid nitrogen is filled, and which extends along the circumference of a core, an outside metal tube which surrounds the inside metal tube with an interval, a cooling vessel of the terminal end connection box to which the inside metal tube is connected, and in which the liquid nitrogen is filled, a heat insulating tube which surrounds the cooling vessel with an interval, an inside bellows tube which connects the end of the outside metal tube and the cooling vessel, and an outside bellows tube which connects the end of the outside metal tube and the heat insulating tube with an interval from the inside bellows tube.
