Summary:To provide a superconduction wire that can achieve a high Q value even when used at a high frequency band.SOLUTION: A superconduction wire has a base material 11, a superconductor layer 13 formed on each of both faces of the base material 11, and a conductive protective layer 14 formed on the surface of each superconductor layer 13. Each conductive protective layer 14 has a thickness that is equal to or lower than 5% of a skin depth when a high-frequency current is flowed to the superconduction wire. The conductive protective layer 14 can be formed from e.g. silver.SELECTED DRAWING: Figure 9 【課題】高周波帯で使用した場合であっても高いＱ値を実現することが可能な超伝導線材を提供することである。【解決手段】本発明にかる超伝導線材は、基材１１と、基材１１の両面の各々に形成された超伝導体層１３と、各々の超伝導体層１３の表面に形成された導電性保護層１４と、を備える。導電性保護層１４の各々の厚さは、超伝導線材に高周波電流を流した際の表皮深さの５％以下である。導電性保護層１４を構成する材料には、例えば銀を用いることができる。【選択図】図９
