PROBLEM TO BE SOLVED: To provide a superconductive cable capable of preventing a damage of a heat-insulating pipe in an accident such as a ground fault; and a cable core for a superconductive cable.SOLUTION: A cable core for a superconductive cable includes: a superconductive conductor layer; a ground layer provided on the outer periphery of the superconductive layer through an electric insulating layer; and a protective layer provided on the outer periphery of the ground layer. The protective layer contains an arc-resistant layer constituted of one or more materials selected from a high-performance and high-function fiber, a polypropylene resin, a polyethylene resin, a polytetrafluoroethylene resin, a silicone resin, an amino resin, an aramid resin, a polyphenylene sulfide resin, a polyimide resin, a polyacrylate resin, a silicone rubber and metal.SELECTED DRAWING: Figure 1 【課題】地絡事故などの事故時に断熱管の損傷を防止できる超電導ケーブル、及び超電導用ケーブルコアを提供する。【解決手段】超電導導体層と、前記超電導導体層の外周に電気絶縁層を介して設けられる接地層と、前記接地層の外周に設けられる保護層とを備え、前記保護層は、高性能・高機能繊維、ポリプロピレン樹脂、ポリエチレン樹脂、ポリ四フッ化エチレン樹脂、シリコーン樹脂、アミノ樹脂、アラミド樹脂、ポリフェニレンサルファイド樹脂、ポリイミド樹脂、ポリアクリレート樹脂、シリコーンゴム及び金属から選択される１種以上の材料から構成される耐アーク層を含む超電導ケーブル用ケーブルコア。【選択図】図１
