PROBLEM TO BE SOLVED: To prevent welding heat from influencing a superconducting coil by setting welding positions at positions distant from the superconducting coil housed in the inside, in a cooling vessel assembled by connecting respective wall parts constituting the cooling vessel to one another by welding. SOLUTION: This cooling vessel wherein the superconducting coil formed by winding a superconducting wire and a cooling medium are housed, and the superconducting coil is cooled with the cooling medium is provided with: a cylindrical inner peripheral wall arranged on the inner peripheral side of the superconducting coil; a cylindrical outer peripheral wall arranged on the outer peripheral side of the superconducting coil; and annular sidewalls connecting both axial edges of the inner peripheral wall and the outer peripheral wall, and respectively arranged on both axial sides of the superconducting coil. Welding parts projecting outward in the axis direction are arranged throughout the total circumference of the inner periphery or/and the outer periphery of the sidewalls, and the welding parts are connected to the axial edges of the inner peripheral wall or/and the outer peripheral wall by welding.
