The purpose of the present invention is to make it possible to use a wider uniform magnetic field space and to achieve an additional use mode for a bulk magnet structure. A bulk magnet structure according to the present invention is provided with a plurality of oxide superconducting bulk bodies arranged so that the central axes thereof are on the same line and at least one outer circumferential reinforcing ring fitted to the bulk magnet structure so as to cover the outer circumferential surfaces of the plurality of oxide superconducting bulk bodies. The plurality of oxide superconducting bulk bodies includes a columnar oxide superconducting bulk body and/or a ring-shaped oxide superconducting bulk body. At least one set of adjacent oxide superconducting bulk bodies are spaced apart from each other in the direction of the central axes thereof. The interior of the bulk magnet structure includes a space through which the central axes pass.
