Claim 0:
1. 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 spaced portion where adjacent metal wires, of the plurality of metal wires, in a circumferential direction are spaced apart from each other, and a joining portion where the adjacent metal wires are joined to each other and a non-joining portion where the adjacent metal wires in the circumferential direction are not joined with each other with the batch plating portion at a part in a cable longitudinal direction of the spaced portion,
wherein a length of the non-joining portion along the cable longitudinal direction is shorter than a winding pitch of the lateral winding shielding portion, and
wherein the non-joining portion comprises a through hole penetrating through the batch plating portion in a radial direction,
further comprising a plurality of the non joining portions where the adjacent metal wires in the circumferential direction are not joined with each other with the batch plating portion at a part in a cable longitudinal direction of the spaced portion,
wherein the plurality of the non joining portions are dispersed discontinuously in the cable longitudinal direction,
wherein the number of the non-joining portions for each 1 meter in the coaxial cable is 10 or more and 20 or less,
wherein a plating layer is disposed on a periphery of each of the plurality of metal wires,
wherein the plating layer remains on a part of the plurality of metal wires being not brought into contact with the batch plating portion, and
wherein a length of the non-joining portion along a longitudinal direction of the plurality of metal wires is shorter than a length of the joining portion along the longitudinal direction of the plurality of metal wires.
