PROBLEM TO BE SOLVED: To provide an oxide superconducting bulk magnet member formed by combining oxide bulk bodies each having an ReBaCuOphase dispersed in an REBaCuOphase, the oxide superconducting bulk magnet member being easy to manufacture and capable of stably obtaining a magnetic field which is intense and symmetrically uniform even when repeatedly magnetized by a pulse magnetizing method or used for a magnet of a rotary machine such as a superconducting electric generator, a superconducting motor, etc.SOLUTION: The oxide superconducting bulk magnet member is formed by combining the oxide bulk bodies each having the ReBaCuOphase dispersed in the REBaCuOphase (where Re is rare earth elements or a combination thereof, x is an oxygen deficiency amount, and 0<x≤0.2), wherein the oxide bulk bodies are arranged in a nesting state obtained by combining shapes including rings, and connected at least at one place by a joint connecting gaps of adjacent oxide bulk bodies arranged in the nesting state. |
