Abstract
A magnetic head suspension assembly includes a support plate coupled to a magnetic head, and a flexible wiring member disposed on the support plate. The flexible wiring member includes a metal plate fixed to the support plate, an insulating layer disposed on the metal plate, a conductive layer disposed on the insulating layer and forming a plurality of conductive lines and connection terminals, and a cover layer on the conductive layer. The connection end portion includes a plurality of the connection terminals, and each of the connection terminals includes a center hole, a first terminal surface that is a surface of the conductive layer and is covered with the cover layer so that the first terminal surface is not exposed during a solder-joining process performed on the connection terminals, and a second terminal surface that is a surface of the conductive layer and faces away from the first terminal surface.
