Abstract
According to one embodiment, a head suspension assembly includes a support plate, a wiring member on the support plate, a head, and a piezoelectric element on the wiring member. The wiring member includes a metal plate and a multilayered member including a first insulating layer, a conducting layer, a second insulating layer, and connection pads formed from the conducting layer. Each of the connection pads is overlaid on a recess formed in the first insulating layer, so as to form a recessed portion along the recess, and the second insulating layer includes an opening opposing each of the connection pads. The piezoelectric element is connected to the connection pads by a conductive adhesive filled in the openings and the recessed portions of the connection pads.
