In accordance with the present invention, a high magnetic field such as 20 T level which has never been achieved with only superconductor at 4.2K can be generated economically with a more compact apparatus than ever, and a coil for generating a high magnetic field can be manufactured with only the Nb.sub.3 Al group superconductor. Therefore, the present invention is significantly effective for a nuclear fusion apparatus of a magnetic confinement type.
