Abstract:
1. A heat insulating type coaxial cable connectable to a superconductive device including at least one element which is operated under a superconductive state, comprising: a center conductor; an insulating member coating the center conductor; and an external conductor attached to the outer periphery of the insulating member and provided at a proper position thereof with a heat insulating portion capable of insulating heat from being conducted into the superconductive filter assembly, wherein the external conductor is composed of a metal plating layer coating the insulating member at the periphery thereof and a resin layer coating the metal plating layer, and the metal plating layer having a cross-sectional area much smaller than that of the canter conductor and the insulating member to serve as the heat insulating portion having a larger heat resistance to resist heat transmission on the metal plating layer.
