    摘要: Disclosed is an actuator device which includes a vibration plate and a piezoelectric element. The vibration plate includes an elastic film which is made of silicon oxide (SiO2) and which is formed on a substrate while the piezoelectric element is formed on the vibration plate and including a lower electrode, a piezoelectric layer and an upper electrode. The vibration plate has such a stress as to give a tensile stress between 300 MPa and 500 MPa, inclusive, to the piezoelectric element that is in a state of being displaced.
