Zusammenfassung:A return-conductor connecting method is for a power direct-current coaxial cable that includes a main conductor at the center, a main insulating layer around the main conductor, and a return conductor that is formed by coaxially stranding a plurality of return-conductor wires around the main insulating layer, in a connecting portion between power direct-current coaxial cables. The return-conductor connecting method includes forming a return-conductor wire bundle by placing a plurality of return-conductor wires next to each other for each of the power direct-current coaxial cables; and welding return-conductor wire bundles of the power direct-current coaxial cables in a butt jointing manner. With this configuration, a method of connecting a return conductor of a direct-current coaxial cable can be provided with which an operation time for welding return-conductor wires can be shortened and which can be applied to a connection of the return conductor between direct-current coaxial cables having different numbers of return-conductor wires.
