PROBLEM TO BE SOLVED: To provide a superconducting magnet capable of maintaining cooling reliability and reducing an eddy current.SOLUTION: A superconducting magnet 1 includes: an annular superconducting coil 2; and an annular cooling member 10 which is provided on the end side of the superconducting coil 2 in the axial direction and cools the superconducting coil 2 by heat transmission. The cooling member 10 has an inner peripheral side slit part 12 which extends over a predetermined length from an end edge 11 on the inner peripheral side of the cooling member 10 to a midway position in the radial direction of the cooling member 10. |
