Patent ID: 8174797

Claim:
A head suspension having a conductive base plate, a piezoelectric element, and a load beam, the piezoelectric element deforming in response to a voltage applied thereto and thereby moving the load beam relative to the base plate in a sway direction, the head suspension comprising: an actuator base integral with the base plate; an auxiliary plate being a discrete part from the base plate and having a surface support and a side support, the surface support facing a periphery of a surface of the piezoelectric element, the side support facing in the sway direction a side face of the piezoelectric element; an attaching part electrically connected to the base plate and formed of the actuator base and auxiliary plate, the attaching part being present between the base plate and the load beam and being configured to attach the piezoelectric element thereto; a nonconductive adhesive layer interposed between the attaching part and the piezoelectric element, to adhere the piezoelectric element to the attaching part; and a conductive material configured to electrically connect an electrode plane of the piezoelectric element and the side support to each other.
