This super non-magnetic soft stainless steel wire rod includes, in mass%, C: 0.08% or less, Si: 0.05% to 2.0%, Mn: more than 8.0% to 25.0% or less, P: 0.06% or less, S: 0.01% or less, Ni: more than 6.0% to 30.0% or less, Cr: 13.0% to 25.0%, Cu: 0.2% to 5.0%, N: less than 0.20%, Al: 0.002% to 1.5%, and C + N: less than 0.20%, with the remainder being Fe and inevitable impurities, in which Md30, which is expressed as Equation (a) described below, is -150 or less. Md �¢ 30 = 413 - 462 �¢ C + N - 9.2 �¢ Si - 8.1 �¢ Mn - 9.5 �¢ Ni - 13.7 �¢ Cr - 29 �¢ Cu |
