PROBLEM TO BE SOLVED: To enhance the performance and the reliability of a superconductive magnet equipped with a cooling-storage-type freezer having a magnetic refrigeration material. SOLUTION: This superconductive magnet consists of a superconductive coil, a radiation shield which surrounds the superconductive coil, a vacuum chamber which surrounds the radiation shield, a cooling-storage-type freezer which cools the superconductive coil with the low-temperature stage and the radiation shield with the high-temperature stage, at least one flexible portion, and a conductive member which thermally connects the superconductive coil and the low-temperature stage.
