摘要：
To provide a high-speed differential cable excellent in transmitting characteristics.
论述类文本阅读SOLUTION: Two signal wires having first dielectric layers 12 ON the outer periphery of internal conductors 11 are prepared at a parallel two core arrangement in the high-speed differential cable 1, a cond dielectric layer 13 is arranged ON the outer periphery of the two-core signal wires, an external conductor 14 is vertically arranged along the outer periphery the cond dielectric layer and a winding layer 15 where a tape-shaped member is spirally wound is prepared ON the outer periphery of the external conductor 14, a drain wire 16 which is located outside the winding layer 15 and at one side of the two-core signal wire is arranged in parallel with the signal wire and an outer cover 17 is arranged ON the outer periphery of the winding layer and the drain wire. Thus and generation of sacking-out of attenuation at a high frequency range is prevented by the external conductor arranged vertically. A good vertically-arranged condition of the external conductor is maintained by preventing scattering of the external conductor with the winding layer and prevention of the sacking-out is not spoiled. Loss is lesned by restraining current generated ON the external conductor since the signal wire is covered by the cond dielectric layer and reduction of the
attenuation is restrained.
