Abstract

The piezoelectric actuator of a head suspension has an actuator base and at least a piezoelectric element, the actuator base connected to the base part of the load beam of the suspension and having at least an opening, the piezoelectric element attached to the opening and deforming in response to a voltage applied thereto to effect displacement of the front end of the load beam. A nonconductive filler is fitted into a circumferential channel defined between a circumferential edge of an opening in the actuator base and a circumferential side face of the piezoelectric element facing the circumferential edge of the opening to maintain a width of the circumferential channel. A nonconductive adhesive part is formed in the circumferential channel and joins the circumferential edge of the opening and the circumferential side face of the piezoelectric element together.
