Provided is a superconducting bulk magnet in which multiple superconducting bulk bodies are combined, wherein it is possible to prevent damage to the superconducting bulk bodies and generate a strong magnetic field. A superconducting bulk magnet in which RE2BaCUO5 is dispersed in a monocrystalline RE1Ba2Cu3Oy (RE is Y or one or more element selected from among rare-earth elements, and 6.8≤y≤7.1), and in which a plurality of superconducting bulk bodies provided with a top surface, a bottom surface, and side surfaces are combined, wherein the superconducting bulk magnet is characterized by having a configuration in which : bulk body units comprising the superconducting bulk bodies and bulk-body reinforcement members disposed so as to cover the side surfaces of the superconducting bulk bodies are disposed so as to be oriented in the same direction and to contact each other to form an aggregate body, the side surfaces of the aggregate body being covered by aggregate-body side-surface reinforcing members, the top and bottom surfaces of the aggregate body being covered by an aggregate-body top reinforcing member and an aggregate-body bottom reinforcing member, and the aggregate-body side-surface reinforcing members, the aggregate-body top reinforcing member, and the aggregate-body bottom reinforcing member being integrated.
