Abstract:
1. A head suspension having a piezoelectric element that deforms in response to a voltage applied thereto, a base having an opening serving as an attaching part to which the piezoelectric element is attached, and a load beam that is fixed to the base so that a front end of the load beam moves in a sway direction according to the deformation of the piezoelectric element, the head suspension comprising: a support formed in the opening, configured to support an electrode surface of the piezoelectric element; and a plurality of laminated adhesive layers formed on the support, to fix the piezoelectric element to the support in a laminating direction in which the adhesive layers are laminated one on another, the plurality of laminated layers being positioned between the support and the piezoelectric element in said laminating direction and one of the laminated adhesive layers that is in contact with the support being electrically insulative.
