PROBLEM TO BE SOLVED: To provide an improved superconducting coil that includes a plurality of parallel conductors and suppresses the circulating currents as much as possible to show stable performance of superconductive wires. SOLUTION: In the superconducting coil, a plurality of superconducting wires A1, A2, A3, A4 are superposed in a radius direction for winding around a cylindrical roll frame 1 with the superconducting wires as coil wires, and the respective superconducting wires are dislocated in the middle of axial winding, and are connected in parallel via a lead wire 3 led from the start and stop ends of winding at both the edges of coils. For each of the superconductive wires A1-A4, the start and stop ends of the winding of the superconductive wires are adjusted to the same position in the circumferential direction of the coils for winding, the termination positions of the start and stop ends of winding are relatively shifted in the circumferential direction of the coils among the respective superconductive wires, and then the leading wires 3-1, 3-2, 3-3, 3-4 connected to the start and stop ends of the winding are axially drawn out for parallel connection.
