Abstract
A head suspension has a piezoelectric element that deforms in response to an applied voltage, a base plate provided with an opening to which the piezoelectric element is attached, and a load beam fixed to the base plate so that a front end of the load beam moves in a sway direction according to deformation of the piezoelectric element. The head suspension includes an adhesive applied to a gap between the piezoelectric element and the opening, to attach the piezoelectric element to the opening. The adhesive has a thixotropic characteristic and is sol when applied to the gap.
