An oxide superconducting wire includes: an oxide superconducting laminate that includes a substrate, an interlayer, and an oxide superconducting layer, in which the interlayer is formed on a main surface of the substrate, and the oxide superconducting layer is formed on the interlayer; an undercoat stabilizing layer that includes a first undercoat stabilizing layer and a second undercoat stabilizing layer and is formed on an outer periphery of the oxide superconducting laminate, in which the first undercoat stabilizing layer is formed of Ag or an Ag alloy so as to cover at least an upper surface of the oxide superconducting layer, and the second undercoat stabilizing layer is formed of one of Cu, Ni, Pb, Bi, and an alloy containing Cu, Ni, Pb or Bi as a major component so as to cover at least a portion of the outer periphery of the oxide superconducting laminate which is not covered with the first undercoat stabilizing layer; and a stabilizing layer that is formed on the undercoat stabilizing layer so as to cover at least a portion of the first undercoat stabilizing layer and a portion of the second undercoat stabilizing layer in the undercoat stabilizing layer. |
