To provide a superconducting coil cooling device which can stably operate a superconducting coil even in a high magnetic field.

This superconducting coil cooling device is provided with containers 16, 18 for maintaining low temperature circumstances, a refrigerating machine 10 installed in the containers 16, 18 to cool the inside of the containers and a superconducting coil 14 connected to the refrigerating machine 10 in the containers 16, 18. The superconducting coil 14 is connected to the cooling stage 10b of the refrigerating machine 10 through a vibration absorbing member 15 made of copper. Further, the vibration absorbing member is interposed between the refrigerating machine 10 and the container 18. The superconducting coil 14 is formed of, for instance, a bismuth series oxide superconducting wire.
