PROBLEM TO BE SOLVED: To provide a superconduction electromagnet apparatus for MRI which not directly transmits the vibration of a gradient magnetic field coil to a superconduction electromagnet, also, acquires a good MR image by reducing the vibration of the gradient magnetic field coil, and miniaturizes the profile of the whole superconduction electromagnet. SOLUTION: In the superconduction electromagnet apparatus for MRI which generates uniform and gradient magnetic fields between the upper and lower part superconduction electromagnets, a supporting material, which supports a helium container, is prepared in the lower part superconduction electromagnet, one end of this supporting material is fixed to the vacuum vessel of the lower part superconduction electromagnet, and the vicinity of the stationary end of the vacuum vessel is fixed to a floor.
