Flexible flat conductor

Flexible flat conductor (1, 20, 30, 40) with a flexible, insulating support structure (2, 21) are applied to the at least one side conductive tracks (3, 4, 5) for transmitting electrical signals, and at least in sections, a magnetic locking surface (6, 12, 15, 27) for shielding of magnetic fields, characterized in that shielded conductors (3, 4, 5) and the magnetic locking surface (12, 15, 27) are arranged to one another such that the flat conductor (1 is folded defined 20, 30) for shielding.
