Oxide superconducting bulk magnet member

An oxide superconducting bulk magnet member comprising:

• a plurality of bulk sections that have outer circumferences with outer circumferential dimensions different from each other and are disposed in a manner such that among the outer circumferences, an outer circumference in which the outer circumferential dimension is relatively large surrounds a small outer circumference;
• and
• interposed sections that are disposed between a pair of the bulk sections that are adjacent to each other,
• wherein a gap is formed between the bulk sections adjacent to each other,
• each of the bulk sections is an oxide bulk in which an RE2BaCuO5 phase is dispersed within an REBa2Cu3O7-x phase,
• a bulk section having a smallest outer circumferential dimension among the bulk sections has a columnar shape or a ring shape, and bulk sections other than the bulk section having the smallest outer circumferential dimension have a ring shape,
• the interposed sections are formed of the oxide bulk to be a bridge portion that connects the pair of the bulk sections that are adjacent to each other, and
• a resin, grease, or solder is included in at least a part of the gap.
