Summary:To provide an MgB2 wire having a small allowable bending radius without extremely decreasing a critical current value and a critical current density of the MgB2 wire.SOLUTION: A superconducting wire includes a plurality of MgB2 wires and a first parent metal. A central point in a region surrounded by the plurality of MgB2 wires is located separately from a central axis of a superconducting wire cross section in a cross section orthogonal to a longitudinal direction of the wire.SELECTED DRAWING: Figure 1 【課題】MgB2線材の臨界電流値や臨界電流密度を極端に低下させることなく、許容曲げ半径の小さなMgB2線材を提供すること。【解決手段】複数のMgB2素線と、第１の母材金属とを有する超電導線であって、線長手方向と直行する断面において、前記複数のMgB2素線で囲まれた領域の中心点と超電導線断面の中心軸とが離れた位置にあることを特徴とする超電導線。【選択図】 図１
