There is established means for providing a superconducting magnet made of a high-temperature bulk superconductor, capable of trapping a high magnetic field with ease and stably. The superconducting magnet made of the high-temperature bulk superconductor, for use by trapping a magnetic field, comprises the bulk superconductor provided with an artificial hole, a low melting metal impregnated into, and filling up at least the artificial hole, and a heat conducting metal material embedded with portions of the high-temperature bulk superconductor, impregnated with, and filled with the low melting metal. The superconducting magnet can be produced by a process comprising steps of providing the artificial hole in the high-temperature bulk superconductor, disposing the heat conducting metal material in at least the artificial hole, applying a process of impregnating and filling up at least the artificial hole with the low melting metal, and subsequently, executing a process of magnetizing.
