Abstract
Provided is an actuator having a piezoelectric element, a diaphragm to which the piezoelectric element is bonded and vibrates according to expansion and contraction displacement of the piezoelectric element, and a first spacer and a second spacer configured to fix both ends of the diaphragm in expansion and contraction displacement direction of the piezoelectric element to a base member. The driving characteristics of the actuator are determined by an effective length of the diaphragm between the first spacer and the second spacer.
