    摘要: A piezoelectric thin film element D, in which a piezoelectric thin film 1 with first and second electrode films 2 and 3 respectively formed on its opposite surfaces in the thickness direction is held by a hold film 5, is fabricated by forming each film 1, 2, 3, and 5 on a film formation substrate 11 and removing the film formation substrate 11 by etching. Even when the hold film 5 is made of material such as resin and therefore exhibits relatively poor adhesion with respect to the other films, the piezoelectric thin film 1 is protected from damage by etchant because the first electrode film 2 which comes into contact with the film formation substrate 11 is formed such that the overall circumference of a peripheral edge portion of the first electrode film 2 laterally extends beyond the lateral surface of the piezoelectric thin film 1 and closely adheres to the hold film 5.

    摘要: A piezoelectric thin film can achieve a large piezoelectric displacement. A chemical composition of the piezoelectric thin film is expressed by Pb1+a(ZrxTi1−x)O3+a(0.2≦a≦0.6 and 0.50≦x≦0.62). The crystal structure of the piezoelectric thin film is a mixture of a perovskite columnar crystal region (24) having an ionic defect in which a portion of the constitutive elements of an oxygen ion, a titanium ion, and a zirconium ion is missing and a perovskite columnar crystal region (25) of stoichiometric composition having no ionic defect. This configuration allows a residual compressive stress in the crystal to be relaxed by the perovskite columnar crystal region (24) having an ionic defect, thus achieving a large piezoelectric displacement (displacement amount).

    摘要: An ink jet including a head body including plural pressure chamber concaves each having a supply port for supplying ink and a discharge port for discharging ink, and a piezoelectric actuator including mutually electrically connected vibration plates that cover the concaves of the head body in order to form pressure chambers together with the concaves and are separately provided correspondingly to one or plural pressure chambers, piezoelectric device respectively provided on surfaces of the vibration plates opposite to the pressure chambers correspondingly to the pressure chambers and individual electrodes respectively provided on surfaces of said piezoelectric devices opposite to said vibration plates for applying a voltage to said piezoelectric devices together with said vibration plates. The vibration plates are deformed in a manner that volumes of the pressure chambers are decreased by applying a voltage to the piezoelectric devices through the vibration plates and the individual electrodes, whereby ink contained in the pressure chambers is discharged through the discharge ports. Additionally, a portion of each of the vibration plates corresponding to each of the pressure chambers is bent into a convex projecting toward an opposite direction to the corresponding pressure chamber due to a compressive internal stress action of each of the piezoelectric devices.
