Summary:PROBLEM TO BE SOLVED: To solve the problem that electrical discharges might occur in air spaces S at leading end sides of stress cones in a prefabricated type joint portion for direct-current CV cables and to enhance insulation performance.SOLUTION: In a prefabricated type joint portion for connecting direct-current CV cables provided with an epoxy unit 2 and stress cones 3, leading end portions of the stress cones 3 are composed of conductive moldings 3c. Since ingress of equipotential lines into air spaces S that exist at leading end sides of the stress cones 3 can be suppressed by the conductive moldings 3c, occurrences of electrical discharges in the air spaces S can be suppressed and insulation performance of a connecting portion can be enhanced.
