PROBLEM TO BE SOLVED : To provide a superconductor for a non-insulated superconducting coil capable of suppressing excitation delay of a coil magnetic field and performing stable and high load energization and a superconducting coil therewith.
SOLUTION : A superconductor for a non-insulated superconducting coil 11 is configured with a bundle 15 obtained by overlapping a plurality of sheets of a tape-shaped superconducting wire rod 14 in which a superconductive layer 13 due to a rare earth oxide superconductor is provided on one surface of a substrate 12. The bundle 15 is configured by superposing 2 to 5 sheets of the superconducting wire rod 14. The superconducting coil 11 is configured by winding the bundle 15 in coil, and is provided with a separating layer 19 having the electric resistance between the bundles 15 wound in coil. As the separating layer 19, for example, a tape made of stainless steel (SUS 316) is used.
