A shielded flat transmission cable for use in wiring electronic appliances having consistent low resistance and a high shielding effect. The cable comprises a plurality of insulated parallel conductors including a grounding conductor and signal transmitting conductors. The conductors and insulating layer are surrounded by a thin metal shielding material. An insulating film surrounds the outer surface of the shielding material. The shielding material is directly and metallically connected to the grounding conductor providing a good electrical contact between the shielding material and the grounding conductor. The connecting means employed can be a spot weld or any other equivalent means directly connecting said grounding conductor and said shielding material. In a first embodiment of the invention the insulation layer, shielding material, and insulating film are formed through lamination. In a second embodiment of the invention they are formed through winding.
