  • Patent number: 6677518
    Abstract: The present invention relates to a data transmission cable and the like including a structure reducing the frequency dependence of cable attenuation in digital transmission, thereby suppressing signal distortions. The data transmission cable includes at least a pair of conductors, each coated with an insulator, extending along a predetermined direction; and a shield tape, provided so as to surround the conductors, including a metal layer. In particular, in the shield tape, the metal layer has a thickness of 1 &mgr;m or more but 10 &mgr;m or less, preferably 2 &mgr;m or more but 6 &mgr;m or less.
