Abstract:
1. A composite superconductor comprising: Superconductor; a friction stir welding (FSW) layer: and a metal body which comprises two or more metal members joined to each other in such a manner that each of the metal members directly covers the superconductor, at least one of the metal members being aluminum or aluminum alloy wherein each of the metal members joined to each other has a groove formed on a joint surface of the metal member, the joint surface being uniform in a longitudinal direction, and the superconductor is placed in the groove so as to contact the respective metal members via at least one of a gap and a heat transfer member which enable to control heat, mechanical or electrical contact conditions between the superconductor and the metal members, said friction stir welding (FSW) layer joining the gap and the heat transfer member and the metal members.
