A superconducting magnet apparatus includes a first superconducting coil centered around an axis extending in a direction intersecting with a vertical direction and a refrigerant circulation circuit through which refrigerant circulates. The refrigerant circulation circuit includes a first cooling pipe path in thermal contact with the first superconducting coil, an upper pipe path arranged above the first cooling pipe path, a lower pipe path arranged below the first cooling pipe path, and a connection pipe path that connects the upper pipe path and the lower pipe path to each other. The first cooling pipe path includes a first storage portion where refrigerant is stored.
