    摘要: 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.

    摘要: An anisotropic conductive film is disclosed, comprising an insulating film having fine through-holes independently piercing the film in the thickness direction, each of the through-holes being filled with a metallic substance in such a manner that at least one end of each through-hole has a bump-like projection of said metallic substance having a bottom area larger than the opening of the through-hole. The metallic substance serving as a conducting path is prevented from falling off, and sufficient conductivity can be thus assured.
