Abstract
In a method of manufacturing piezoelectric actuators, a vibrating body plate supporting vibrating bodies at vibrational nodes thereof and a moving body plate having moving bodies are provided. Each of the vibrating bodies has a vibrator and a piezoelectric body mounted on the vibrator. The vibrating body plate and the moving body plate are stacked over one another to provide a piezoelectric actuator assembly. The piezoelectric actuator assembly is then cut at the vibrational nodes of the vibrating bodies to provide individual piezoelectric actuators.
