Disclosed is a superconducting apparatus comprising a superconducting coil and a cooling apparatus for cooling this superconducting coil. The cooling apparatus is constituted by a cooling medium circulating path for subjecting a cooling medium to a vaporization/liquefication cycle, and a temperature equalizing plate for effecting a uniform cooling of the superconducting coil by the cooling medium. The cooling medium circulating path is constituted by a pair of flowing-down parts through which a liquid cooling medium flows downwards by gravity, and a pair of vaporization parts through which the liquid cooling medium flows upwards while it is being vaporized. The temperature-equalizing plate covers the peripheral surface making one entire round of the superconducting coil around the axis of the coil. It is divided into at least two parts at its lower end, which are electrically insulated from each other.
