Coaxial cable

A coaxial cable comprising:

• a central conductor consisting of three single element twisted wires, the central conductor having an outer diameter and the three single element twisted wires having a twist pitch that is between 11 and 16 times the outer diameter of the central conductor;
• a fluororesin insulation extruded on and covering the central conductor such that all of the twisted single element wires of the central conductor contact the fluororesin insulation as observed in in a plane perpendicular to the longitudinal direction of the cable, the fluororesin insulation being a non-foam insulation material and voids being provided between portions of the central conductor and an inner surface of the fluororesin insulation;
• an outer conductor disposed on the external periphery of the insulation;
• and
• a jacket for covering the outer conductor,
• wherein the adhesive force between the central conductor and the insulation and a breaking strength of the central conductor have the following relationship:
• adhesive force ≦⅓ breaking strength.
