Abstract
A head suspension has a load beam and a piezoelectric actuator. The piezoelectric actuator has an actuator base connected to a base part of the load beam and a piezoelectric element attached to an opening formed in the actuator base. The piezoelectric actuator displaces a front end of the load beam in a sway direction according to deformation of the piezoelectric element that occurs in response to a voltage applied thereto. The head suspension includes a nonconductive adhesive filled between the piezoelectric element and the opening, to fix the piezoelectric element to the opening and a trap formed on the actuator base outside the opening, to hold the nonconductive adhesive oozing out of the opening and prevent the oozed adhesive from spreading. The trap prevents the oozed adhesive from contaminating the periphery of the opening.
