PURPOSE:To prevent the mechanical and thermal damage of a bar-shaped oxide superconductor by improving the structure of a lead on low temperature side. CONSTITUTION:In a current lead, which consists of the series-connected body composed of the lead 2 on the high temperature side consisting of a well conductive metal and the lead 15 on the low temperature side consisting of an oxide superconductor and is cooled with refrigerant gas GHe at low temperature, the lead 15 on low temperature side consists of the series-connected body composed of the bar-shaped oxide superconductor 18 conductively coupled between a middle coupling metal fitting 6 and a lower coupling metal fitting 20 and the flexible conductor 21 conductively coupled between a low coupling metal fitting and a low-temperature terminal metal fitting 19, and it is accommodated in the tubular container 17 for coupling the middle coupling metal fitting and the low-temperature terminal metal fitting. |
