Method of manufacturing piezoelectric actuator

A method of manufacturing piezoelectric actuators, comprising the steps of:

• forming a vibrating body plate having vibrating bodies by mounting piezoelectric bodies on resilient bodies;
• forming a moving body plate having moving bodies;
• forming a pressure application plate having a pressure application member for applying pressure to said vibrating bodies and to said moving bodies;
• stacking said vibrating body plate, said moving body plate, and said pressure application plate on top of each other to constitute a piezoelectric actuator assembly;
• and
• cutting said piezoelectric actuator assembly into individual piezoelectric actuators, thereby taking out the piezoelectric actuators.

A method of manufacturing piezoelectric actuators, comprising the steps of:

• forming a vibrating body plate having a vibrating body constructed of a resilient material to which a piezoelectric body is mounted, said vibrating body being connected with said vibrating body plate at connector portions formed at vibrational nodes of said vibrating body;
• separating said vibrating body from said vibrating body plate;
• and
• stacking said vibrating body and said moving body on top of each other.

A method of manufacturing piezoelectric actuators, comprising the steps of:

• forming a vibrator plate constructed of a resilient material and having a vibrator, said vibrator plate being connected with said vibrator at connector portions formed at vibrational nodes of a vibrating body where a piezoelectric body is stuck to said vibrator;
• separating said vibrator from said vibrator plate at said connector portions;
• forming said vibrating body constructed of said vibrator to which said piezoelectric body is stuck;
• and
• stacking said vibrating body and said moving body on top of each other.
