    摘要： Tape-shaped superconducting wires are made by forming a superconducting film on the substrate. At least the superconducting film is slit, electrically separated into a plurality of superconducting film parts each having a rectangular cross section and arranged in parallel to form parallel conductors. This provides superconducting wires capable of containing AC loss. A superconducting coil is made by winding the superconducting wires described above, wherein the provision of a coil structure containing at least partially a part wherein the perpendicular interlinkage magnetic flux acting among various conductor elements of the parallel conductors by the distribution of the magnetic field generated by the superconducting coils cancel mutually enables a simple structure without transposition to cancel mutually the interlinkage magnetic flux by the perpendicular magnetic field against wires, to contain circulating current within the wires by the perpendicular magnetic field and to make shunt current uniform. This provides a low-loss superconducting coil.
