ABSTRACT:
A piezoelectric/electrostrictive film type actuator is provided including a ceramic substrate and a piezoelectric/electrostrictive device disposed on the ceramic substrate that is provided with a plurality of piezoelectric/electrostrictive films and electrode films. The device is driven by displacement of the piezoelectric/electrostrictive device. The piezoelectric/electrostrictive device includes a plurality of layers of piezoelectric/electrostrictive films, and the piezoelectric/electrostrictive films and electrode films are alternately laminated such that an electrode film forms an uppermost layer and a lowermost layer of the piezoelectric/electrostrictive device.
