Abstract
A shielded wire having a central core and an insulation layer coated thereover. A shield layer separates the insulation layer from a ground wire and is formed by a composite tape having a metal surface and an adhesive surface. The metal surface is longitudinally folded to cover a portion of the adhesive surface and the tape is helically wound with the folded surface on the outside to form alternate helical patterns of the metal and adhesion layers. A sheath covers the shield layer and the ground wire and is bonded to the adhesive layer while the ground wire is in contact with the outside metal layer. The inside metal surface forms the shield.
