PROBLEM TO BE SOLVED: To obtain a superconducting device which can increase the output of a superconductive power storage system while reducing the manufacturing cost of the superconducting coil of the system. SOLUTION: A superconducting device is constituted by convergently arranging a plurality of short cylindrical superconducting solenoid coils 1aa, 1ab, 1ac, in each of which superconducting coils 1 are coaxially arranged in the longitudinal direction in a plurality of coaxial rows and electrically connecting the coils 1aa, 1ab, and 1ac in parallel with each other. In addition, the output of the superconducting device is increased without reducing the stored energy of the device by making currents evenly flow to each solenoid coil by making the self-inductance of the solenoid coils at axially both ends larger than those of the solenoid coils at their axially central parts. |
