PURPOSE:To provide a superconductive conductor with refrigerant easy to flow by equipping in a casing a rod-shaped superconductor and a refrigerant passage to cool superconductor directly. CONSTITUTION:Refrigerant flows in a refrigerant path 3 formed by spacers 4 interposed between a casing 2 and a rod-shaped superconductor 10. The spacers 4 are arranged at several points on the superconductor 10 at a certain spacing, wherein a major part of the superconductor 10 is cooled by the refrigerant flowing in the refrigerant path 3 directly without the aid of spacers 4. Thus the superconductor is cooled directly with refrigerant path secured, so that it is easy for the refrigerant to flow and the superconductor is cooled effectively.
