PURPOSE: To obtain a superconducting coil in which respective superconducting wires are bonded firmly without lowering the operability of a winding operation and which can eliminate the fear of a quenching operation by a method wherein the cross-sectional shape of every superconducting wire is formed to be an oval shape and the arrangement of the cross section of coils by the superconducting wires which are wound in a plurality of rows and a plurality of steps is formed to be lattice-shaped. CONSTITUTION: Superconducting wires 1A which use a drawn material having an oval shape are wound in such a way that every short-diameter side 1a of the oval shape is wound in the up-and-down direction, and every close contact face having a narrow area is formed on opposite faces 1b of the superconducting wires 1A which are adjacent in a plurality of rows and a plurality of steps. Then, the cross section of coils by the respective superconducting wires 1A is arranged to be lattice-shaped, gaps 2A are formed on the outer circumference of the respective arranged coils, the gaps 2A as a whole are impregnated with an insulating resin, and the coils are brought into close contact by a tightening force by a glass cloth 3. Thereby, it is possible to obtain a superconducting coil in which the respective superconducting wires 1A are bonded firmly without lowering the operability of a winding operation and which eliminates the fear of the generation of a quenching operation. |
