Abstract
In a method of manufacturing a piezoelectric actuator there are provided a piece of piezoelectric material having piezoelectric bodies, a first piece of material having vibrational bodies, a second piece of material having movable bodies, and a third piece of material having pressurizing members. The first, second and third pieces of materials are superimposed over the piece of piezoelectric material to form a multilayered structure having piezoelectric actuators. The multilayered structure is cut to separate each of the piezoelectric actuators from one another.
