To provide a superconducting wire that can suppress a quenching burning accident.SOLUTION: A superconducting wire of an embodiment includes an oxide superconductor layer. The oxide superconductor layer has a continuous Perovskite structure including rare earth elements, barium (Ba), and copper (Cu). The rare earth elements include a first element which is praseodymium (Pr), at least one second element selected from the group consisting of neodymium (Nd), samarium (Sm), europium (Eu), and gadolinium (Gd), at least one third element selected from the group consisting of yttrium (Y), terbium (Tb), dysprosium (Dy), and holmium (Ho), and at least one fourth element selected from the group consisting of erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu).SELECTED DRAWING: Figure 1 【課題】クエンチ焼損の抑制が可能な超電導線材を提供する。【解決手段】実施形態の超電導線材は、酸化物超電導層を備える。酸化物超電導層は、希土類元素、バリウム（Ｂａ）、及び、銅（Ｃｕ）を含む連続したペロブスカイト構造を有し、上記希土類元素は、プラセオジウム（Ｐｒ）である第１の元素、ネオジウム（Ｎｄ）、サマリウム（Ｓｍ）、ユウロピウム（Ｅｕ）及びガドリニウム（Ｇｄ）の群の少なくとも一種類の第２の元素、イットリウム（Ｙ）、テルビウム（Ｔｂ）、ジスプロシウム（Ｄｙ）及びホルミウム（Ｈｏ）の群の少なくとも一種類の第３の元素、並びに、エルビウム（Ｅｒ）、ツリウム（Ｔｍ）、イッテルビウム（Ｙｂ）及びルテチウム（Ｌｕ）の群の少なくとも一種類の第４の元素を含む。【選択図】図１
