ABSTRACT:
A superconductive cable capable of promoting a heat insulating function by a heat insulating tube. A heat insulating tube contained within a cable core of a superconductive cable includes a first metal tube and a second metal tube and a third metal tube arranged from an inner side in a diameter direction. An inner side heat insulating portion is formed between the first metal tube and the second metal tube, and an outer side heat insulating portion is formed on an inner side of the third metal tube and on an outer side of the inner side heat insulating portion. A heat insulating function of the heat insulating portion on an outer side is set to be lower than a heat insulating function of the heat insulating portion on an inner side thereof.
