Abstract
A flexible wiring board that can bridge wires and also can prevent production of conductive foreign materials in use, to secure good performance of a magnetic head. The flexible wiring board for connecting therethrough a suspension substrate having mounted thereon a magnetic head of a hard disk drive and a control circuit substrate for actuating the magnetic head includes a short-circuit forming portion for forming a shorting portion for bridging wires to prevent electrostatic destruction of the magnetic head; and a cut for removing the shorting portion. When the flexible wiring board is cut along the cut, the shorting portion can be removed without producing conductive foreign material resulting from the cutting off of the shorting portion.
