In a superconducting magnets for MRI configured to generate a homogeneous magnetic field and a gradient magnetic field in a space between a top superconducting magnet and a bottom superconducting magnet, the bottom superconducting magnet is provided with a supporting member that supports a helium vessel, and the supporting member is fixed to a vacuum vessel of the bottom superconducting magnet at one end, and is fixed to the floor surface in the vicinity of the end fixed to the vacuum vessel. A high-quality MR image can be thus obtained by preventing direct transmission of oscillation of the gradient coils to the superconducting magnet and reducing oscillation of the gradient coils while achieving a reduction of the overall superconducting magnet in size.
