PROBLEM TO BE SOLVED: To provide an inexpensive superconductive coil capable of generating a high magnetic field even at a relatively high temperature, and to provide a superconductor used for the superconductive coil. SOLUTION: In the superconductive coil in a pan cake shape where a superconductive wire is wound, the superconductor is wound, where a superconductive wire in a tape shape (Bi, Pb) 2223 and a superconductive wire in a tape-like thin film RE123 are electrically connected in series so that the superconductive wire in a tape shape (Bi, Pb) 2223 and the superconductive wire in a tape-like thin film RE 123 are arranged at an outer periphery and an inner periphery, respectively.
