A head suspension has a base plate 11a, a load beam 13a, and a piezoelectric element 40 that is arranged between the base plate and the load beam and deforms in response to applied power to precisely move a front end of the load beam relative to the base plate. The head suspension includes an opening 20 formed in the base plate and configured to receive the piezoelectric element and a support member 19 joined with the base plate, partly protruding into the opening, and configured to support an electrode 71 of the piezoelectric element. The support member 19 integrally has a base end support 19a1 to support a base end of the electrode, a front end support 19a2 to support a front end of the electrode, and a pair of support links 19a3 to connect the base end support and front end support to each other outside the piezoelectric element. This configuration reduces the number of parts to support the piezoelectric element.
