| 摘要 |
The present invention provides a small-diameter coaxial cable in which the same electrical and mechanical characteristics as in the prior art can be maintained and costs do not increase. The coaxial cable comprises a central conductor including three twisted wires and having a cross-sectional area of 0.005 mm2 or less, a fluororesin insulation for covering the central conductor, an outer conductor disposed on the external periphery of the insulation, and a jacket for covering the outer conductor. The adhesive force between the central conductor and the insulation is one third or less the tensile strength of the central conductor. The method for manufacturing the coaxial cable comprises twisting three wires together to form a central conductor having a cross-sectional area of 0.005 mm2 or less, extruding a fluororesin and forming an insulation on the central conductor so that adhesive force with the central conductor is one third or less the tensile strength of the central conductor, and providing the insulation with an outer conductor and a jacket.
