Abstract
A suspension comprises a load beam fitted with a flexure, an actuator base including a base plate, a hinge member thinner than the base plate, and a pair of piezoelectric ceramic elements. The piezoelectric ceramic elements displace the distal end portion of the load beam in a sway direction when supplied with voltage. Each piezoelectric ceramic element is stored in an opening portion in the actuator base. An electrical insulating cover film is pasted on each piezoelectric ceramic element. The cover film covers the opposite side faces of each piezoelectric ceramic element. The opposite end faces of each piezoelectric ceramic element are covered with an adhesive agent that fixes the element to the actuator base.
