PROBLEM TO BE SOLVED: To provide a superconductive coil capable of preventing occurrence of a quench phenomenon without strongly constraining a superconductive wire. SOLUTION: This super conductive coil is structured to be excited at an ultralow temperature, and provided with: a winding frame 10 including a cylindrical shaft part 11, and a pair of flange parts 12 and 13 extended in a radially-outer direction from both axial ends of the shaft part 11; a superconductive wire 20 spirally wound around the outer periphery of the shaft part 11, and impregnated with a resin in its wound state; and a reinforcing material 50 connected to both the pair of flange parts 12 and 13 at least at an ultralow temperature, and restraining the pair of flange parts 12 and 13 from coming close to each other by thermal contraction.
