Provided is a laminated and fixed structure of a plurality of superconducting bulk bodies (2a-2c), in which a fixing ring (5, 5a-5ac) which is provided for each superconducting bulk body (2, 2a-2c) and fixed to an outer periphery of the superconducting bulk body (2, 2a-2c) includes a screw portion, and the adjacent bulk bodies (2a-2c) are laminated and fixed by fitting the screw portions of the adjacent fixing rings (5, 5a-5ac) at the time of laminating. |
