Abstract
An oxide superconductor current lead in which generation of Joule heat at joint portions with a system side conductor and a power supply side conductor is reduced with use of an oxide superconductor with less heat penetration into a super conducting equipment system is provided. A columnar oxide superconductor molten bodies (interelectrode superconductor, in-electrode superconductorsand) are produced, the in-electrode superconductorand a left end portion of the interelectrode superconductorare placed into a power supply side metallic electrode, and the in-electrode superconductorand a right end portion of the interelectrode superconductorare similarly placed in a system side metallic electrode, then degassed joining metal is used to join them to form an oxide superconductor current lead, a power supply side conductorfrom a power supply is joined to the power supply side metallic electrode, and a system side conductorfrom a superconducting system side is joined to the system side metallic electrodewith use of respective clampsand
