A suspension for disc drive 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. A covering material such as an adhesive agent that fills the space between the peripheral edge portion of the piezoelectric ceramic element and the actuator base forms a cover portion that covers the opposite end faces and the opposite side faces of the ceramic element.
