A cable assembly extends in a longitudinal direction. The cable assembly comprises a first cable, two second cables, two coupling portions, an interposing portion and an outer cover. The first cable has a first conductor and a first cover. Each of the second cables has a second conductor and a second cover. The coupling portions couple the second covers, respectively, with the first cover. The first cable, the two second cables and the two coupling portions are arranged in a V-shape in a plane perpendicular to the longitudinal direction. The interposing portion extends along the first cable and the two second cables and has a full length which is equal to that of each of the first cable and the two second cables. The interposing portion is brought into contact with all the first cable and the two second cables.

In accordance with an aspect of the disclosure, a cable comprises a flexible cable portion; and an end cable portion connected to one end of the flexible cable portion, wherein the flexible cable portion comprises: a first wire comprising one or more signal transmission lines; and a second wire comprising one or more fill-cut areas corresponding to the signal transmission lines and at least one or more ground lines.
