Coaxial cable, coaxial cable producing method, and cable assembly

A coaxial cable, comprising:

• a conductor;
• an electrically insulating member provided over a periphery of the conductor;
• a shielding layer composed of served shields including a plurality of metal wires helically wrapped around a periphery of the electrically insulating member to be provided over a periphery of the electrically insulating member;
• and
• a sheath provided over a periphery of the shielding layer,
• wherein the electrically insulating member includes indentations on portions of a surface of the electrically insulating member to be brought into contact with the plurality of metal wires respectively,
• wherein the indentations on the electrically insulating member are mated to the plurality of metal wires respectively,
• wherein the shielding layer is configured in such a manner that first circumferential portions of the plurality of metal wires being brought into contact with the electrically insulating member are mated to the indentations, respectively, on the electrically insulating member, second circumferential portions of the plurality of metal wires are provided radially outwardly with respect to the first circumferential portions, and adjacent ones of the plurality of metal wires in a circumferential direction of the shielding layer are brought into surface contact with each other,
• wherein each of the first circumferential portions has an arc shape while each of the second circumferential portions has a flat shape, and
• wherein, at a cross section perpendicular to a longitudinal direction of the coaxial cable, not shorter than ⅙ lengths of outer circumferential lengths of the plurality of metal wires are mated to the indentations, respectively, on the electrically insulating member,
• wherein the plurality of metal wires include wire contact portions, and wherein the plurality of metal wires are in contact with each other,
• wherein the electrically insulating member includes at least one protruded portion formed on an outer peripheral surface of the electrically insulating member, and
• wherein a gap is provided between the at least one protruded portion of the electrically insulating member and the wire contact portions of the plurality of metal wires.
