An electric cable, in particular a data transmission cable, includes at least one line, in particular several twisted-pair lines, a screening sheet for the at least one line which screening sheet includes at least one substrate layer of a plastic material and at least one screening layer of an electrically conductive material, in particular metal, which the substrate layer is lined with, wherein the screening layer being provided with spacing gaps for electrical interruption thereof in a longitudinal strip direction, with the spacing gaps extending crosswise of the longitudinal strip direction and recurring at longitudinal intervals, an external envelope of an insulating material, and a semi-conductive shielding layer arranged between the screening sheet and the external envelope.
