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