摘要： A high-speed differential cable (1) comprises two-core signal lines in each of which a first dielectric layer (12) is provided around the perimeter of an internal conductor (11), which are arranged so that the cores thereof are in parallel, a second dielectric layer (13) provided around the perimeter of the two-core signal lines, drain lines (14) which are disposed outside the second dielectric layer and at both sides of the two-core signal lines, respectively, and arranged in parallel to the signal lines, an external conductor (15) which is provided longitudinally around the perimeter of the second dielectric layer and the drain lines, with the insulative side thereof arranged outside and the conductive side thereof arranged inside, a casing (16) provided around the perimeter of the external conductor, and drain line trenches (17) provided at the perimeter of the second dielectric layer, where the drain lines are disposed. In each of the drain line trenches (17), at least part of the circumference of the drain line can be engaged. Since the signal lines and the drain lines can be thereby arranged symmetrically with high precision, it is possible to ensure excellent electrical balance of the two cores of the signal lines and obtain excellent electrical property and excellent transmission property. Further, since the external conductor is provided longitudinally, it is possible to prevent the suckout of attenuation in a high frequency region.
