Abstract
A coaxial cable is composed of a conductor, an insulator around the conductor, a shield layer around the insulator, and a sheath around the shield layer. The shield layer includes a lateral winding shielding portion with metal wires helically wrapped around the insulator, and a batch plating portion covering the lateral winding shielding portion. The shield layer includes a joining portion where adjacent metal wires are joined with each other with the batch plating portion at a gap between the adjacent metal wires, and inner peripheral portions where the metal wires are not being covered with the batch plating portion and plating layers are exposed. The joining portion is provided between adjacent inner peripheral portions. When an elemental analysis is performed in any analysis region having an area of 0.015 mmor more and 0.300 mmor less in an insulator-side surface of the shield layer which is stripped from the insulator, an area of a chlorine present region where chlorine is present in the analysis region is 5% or less of an area of the analysis region.
