In a method for producing a multi-core shielded cable comprising a shielding layer arranged on the outer peripheral side of the, and an outer sheath layer arranged on the outer side of the shielding layer, the tape has an overlap margin on the core assembly. A method for producing a multi-core shielded cable, characterized in that the overlap margin is fused by a heat-welding portion immediately after winding.
