PROBLEM TO BE SOLVED: To improve the connection strength.SOLUTION: Provided is a connection structure 100 of two superconductive wire rods 10A and 10B each having an oxide superconductive conductor layer 3 formed on one face side of a base material 1. The oxide superconductive conductor layers are bonded in a face-to-face manner in the connection ends of the two superconductive wire rods 10A and 10B, and a filling material 6 for reinforcement is provided from the superconductive wire rod 10A through the other superconductive wire rod 10B along the thickness direction of the superconductive wire rods. The filling member 6 for reinforcement improves the strength for a stress in the shearing direction in the connection ends. Accordingly, the connection strength of the wire rods can be improved.SELECTED DRAWING: Figure 2 【課題】接続強度を向上させる。【解決手段】基材１の片面側に酸化物超電導導体層３が形成された二本の超電導線材１０Ａ，１０Ｂ同士の超電導線材の接続構造１００であって、二本の超電導線材１０Ａ，１０Ｂの接続端部において、酸化物超電導導体層が向かい合わせで接合されており、超電導線材の厚さ方向について、一方の超電導線材１０Ａから他方の超電導線材１０Ｂに渡って補強用の埋め込み材６が設けられている。この補強用の埋め込み材６により、接続端部における剪断方向の応力に対して強度が向上し、これに伴い、線材の接続強度が向上する。【選択図】図２
