Patent ID: 8653712

Claim:
A superconducting coil comprising: a superconducting material wire coated with an insulation material and; a coil frame on which the superconducting material wire is wound, the coil frame comprising a first member which comprises a thin plate in a ring shape and includes a pair of straight portions, and a second member jointed with a first inner periphery portion of the first member, the second member extending from the jointed portion with the first member toward an outer periphery of the first member, wherein the first member includes a curved joint portion which connects the pair of the straight portions and which is bent to form a curved plane with a three-dimensional shape, and wherein the superconducting material wire is wound between the first member and the second member, which constitute the coil frame, and the wound superconducting material wire is shaped in accordance with the ring shape of the first member.
