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： The method of manufacturing an ink-jet head of this invention includes the steps of forming plural individual electrodes and plural piezoelectric devices stacked in this order on a supporting substrate; flattening a top surface of the supporting substrate including the individual electrodes and the piezoelectric devices by filling a filler in a portion on the supporting substrate where the individual electrodes and the piezoelectric devices are not formed up to substantially the same level as a level of upper surfaces of the piezoelectric devices; forming a common electrode on the entire flattened top surface of the supporting substrate; fixing a pressure chamber part for forming pressure chambers on the common electrode; and removing the supporting substrate after fixing the pressure chamber part on the common electrode. Thus, the entire plane on which the common electrode is to be formed is flattened before forming the common electrode.

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.

摘要： Formed on a surface of an oscillation plate on the side of a head main body portion is an intermediate layer having a window portion through which a displacement portion of the oscillation plate is exposed to a pressure chamber. The intermediate layer and a compartmenting wall of the main body portion are adhered together by an adhesive of electro-deposition resin. The intermediate layer is formed of copper, having a thickness of 5 &mgr;m, so that, when a part of the adhesive is forced out, such a forced-out adhesive portion will not adhere to the displacement portion of the oscillation plate.
