PROBLEM TO BE SOLVED : To provide a superconducting bulk magnet which is hardly cracked even during the course of magnetization in a high magnetic field of 10 T order and can be used as a high power magnetic field generating source. SOLUTION : A superconducting bulk magnet comprises : a superconducting bulk body in which RE2BaCuO5 (RE is one element or two or more elements selected from Y or a rare earth element) is finely dispersed into RE1Ba2Cu3Oy (y represents an oxygen amount and satisfies 6.8≤y≤7.1); and a reinforcing ring surrounding the superconducting bulk body. In the superconducting bulk magnet, an inner diameter d1 of the reinforcing ring at room temperature and an outer diameter d2 of the superconducting bulk body satisfy a relationship of d1
