The present invention provides an oxide superconducting bulk magnet which can obtain a sufficient amount of total magnetic flux, by preventing the superconducting bulk body from being broken due to electromagnetic stress and quenching phenomenon to enable magnetization by a strong magnetic field. An oxide superconducting bulk magnet comprising an oxide superconducting bulk body wherein RE 2 BaCuO 5 is dispersed in a monocrystalline RE 1 Ba 2 Cu 3 O y ; and an outer peripheral reinforcing ring fitted to the outer periphery of the oxide superconducting bulk body, wherein the outer peripheral reinforcing ring is made of a plurality of metal rings having a multiple ring structure in the radial direction, at least one of the plurality of metal rings has a thermal conductivity of 20 W/(m·K) or more at a temperature of 20 to 70 K and at least one of the plurality of metal rings has a higher strength than the metal ring having a thermal conductivity of 20 W/(m·K) or more.
