Abstract:
A data transmission cable comprising: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 said conductors, including a metal layer facing said conductors, said metal lave having a thickness of 1 &mgr;m or more but 10 &mgr;m or less; wherein said metal layer has a thickness which is 50% or more but 300% or less of the skin thickness given by the following expression: 1Ï€&CenterDot;Î´&CenterDot;Î¼&CenterDot;fâ€ƒwhere f is the fundamental frequency (Hz) of digital signals transmitted, &dgr; is the conductivity (mho/m) of said metal layer, and &mgr; is the magnetic permeability (H/m) of said metal layer.
