Coaxial cable and cable assembly

A coaxial cable comprising:

• a conductor;
• an insulator covering a periphery of the conductor;
• a shield layer covering a periphery of the insulator;
• and
• a sheath covering a periphery of the shield layer,
• wherein the shield layer includes a lateral winding shielding portion comprising a plurality of metal wires being helically wrapped around the periphery of the insulator to cover the periphery of the insulator, and a batch plating portion comprising a hot dip plating, which is covering a periphery of the lateral winding shielding portion,
• wherein the shield layer includes a joining portion where the plurality of metal wires adjacent to each other in a circumferential direction are joined with each other with the batch plating portion at a gap where adjacent ones of the plurality of metal wires are spaced apart from each other,
• wherein the shield layer includes inner peripheral portions where the plurality of metal wires are not being covered with the batch plating portion and plating layers are exposed,
• wherein the joining portion is provided between adjacent inner peripheral portions of the inner peripheral portions,
• wherein the shield layer includes outer peripheral portions where the plurality of the metal wires are being covered with the batch plating portion,
• wherein an outer peripheral portion of the outer peripheral portions includes an intermetallic compound between the plurality of metal wires and the batch plating portion,
• wherein the shield layer is configured to be higher in electrical conductivity in an inner peripheral portion of the inner peripheral portions than the outer peripheral portion, and
• wherein an outer peripheral surface of the joining portion is located radially outward with respect to outer peripheral surfaces of the outer peripheral portions.
