Abstract
In one embodiment, a superconducting magnet configured to be used in an MRI apparatus that includes a gradient coil. The superconducting magnet comprising a helium vessel, a vacuum vessel, and a heat shield. Among components constituting the heat shield, at least a component of a portion facing the gradient coil is composed by superimposing two layers of metallic materials, the two layers being a first shield layer and a second shield layer. The first shield layer is disposed in such a manner that distance between the gradient coil and the first shield layer is shorter than distance between the gradient coil and the second shield layer, and a metallic material forming the first shield layer is higher in electrical conductivity than a metallic material forming the second shield layer.
