The present invention is a superconduction stabilizer material used in a superconducting wire. The stabilizer material comprises a copper material containing a total of 3 to 400 ppm by mass of one or more additional elements selected from among Ca, La and Ce, with Cu and inevitable impurities as the remainder. The total concentration of the inevitable impurities other than the gas components O, H, C, N and S is 5 to 100 ppm by mass. |
