Abstract
A conductor obtained by connecting a plurality of superconductors by normal conductivity or a conductor comprised of superconductors and normal conductors, said low resistance conductor using superconductors characterized in that an apparent specific resistance of said conductor at below a superconducting transition temperature of said superconductors is lower than the specific resistance of copper at that superconducting transition temperature.
