Abstract

The present invention provides a terminal structure of a superconducting cable including a cable core having a superconducting shield layer and an electrical insulation layer. The superconducting shield layer has a radially outer portion provided with by a connection electrode and the superconducting shield layer and the connection electrode are connected together with a low melting solder. The connection electrode has a ground wire connected thereto to ground the superconducting shield layer. For a multiphase cable including a plurality of cable cores, connection electrodes are linked by a conductive coupling member to short circuit superconducting shield layers. The superconducting shield layer can be grounded without impaired insulating property of the electrical insulation layer.
