Conductive member, disk drive using same, and conductive member fabricating method

摘要

Embodiments of the present invention provide a conductive member, in which electric characteristics can be improved by matching impedance all the way from a conductive wire to a pad. In one embodiment, a conductive member comprises: a back side metal layer; an insulating layer formed on the back side metal layer; a conductive wire formed on the insulating layer; and a pad formed on the insulating layer and electrically connected to the conductive wire; at least one opening and at least one supporting structure being formed at a position corresponding to the pad on the back side metal layer.
