The invention relates to an electric cable having at least one central core and a screen surrounding the central core and electrically insulated therefrom. According to the invention, the screen is constituted by a composite tape comprising an insulating substrate and at least one layer of metal deposited on the substrate, one of the two longitudinal edges of the tape overlaps the other edge, and the two edges are welded together by ultrasound until the portions of the metal layers of the two longitudinal edges come into contact, thereby providing electrical continuity. This type of cable can be used in the field of broadband telecommunications.
