PROBLEM TO BE SOLVED: To provide a flexible flat cable (FFC) sheathed with a shield material and a manufacturing method thereof achieving high reliability of connection between the shield material and a ground conductor. SOLUTION: A plurality of flat-square conductors 4 are arranged in parallel with each other to form a conductor group. An insulating film 2c having an insulating adhesive layer 2b is bonded to each of top and bottom surfaces of the conductor group with the adhesive layer 2b facing inward, and they are integrated to form the FFC 2. The FFC 2 is formed such that the insulating film 2c is partially removed to thereby expose the ground conductor 3 from the surface of the FFC 2, and the FFC 2 and the shield material 1 are bonded to each other. Then, a metal plate 6 is placed on the shield material 1, and the exposed portion of the ground conductor 3 formed at the surface of the FFC 2 is electrically connected to a shield metal 1b of the shield material 1 and the metal plate 6 by ultrasonic bonding.
