摘要： This invention provides a piezoelectric actuator, concerning which a substrate and a piezoelectric film layer will never erode, the area of which can be enlarged, and which has a flat top surface, and this invention provides an ink jet printing head, a printer, a method for manufacturing a piezoelectric actuator, and a method for manufacturing an ink jet printing head. A piezoelectric actuator comprising a piezoelectric film held between a lower electrode and an upper electrode is characterized in that columnar crystal grains of piezoelectric ceramic which composes the piezoelectric actuator are random-oriented in a film thickness direction, and that a mean diameter of the columnar crystal grains is in the range of 100 nm to 15000 nm. The step of forming precursor films (411, 412,...), which are composed of metal and oxygen, over a lower electrode (32) is followed by the step of giving hydrothermal treatment by dipping the precursor films (411, 412,...) in an alkaline solution (101), which has 2 M[mol/l] or less, more preferably 0.1 M[mol/l] or less, concentration of a given alkaline solute, and by promoting the crystallization under certain conditions. Since a strong alkaline solution is not used, there is no fear that a substrate or a piezoelectric film layer may erode.

摘要： When a piezoelectric material is manufactured by hydrothermal method, the proper amount of lead contained in the piezoelectric film can be ensured and decreases in piezoelectric characteristics can be prevented. A method for manufacturing a piezoelectric material expressed by the formula ABO 3 , containing an element "a" as the element expressed by A above, and having a perovskite crystal structure, comprises a first step of producing an oxide containing an element "a'", and a second step of producing a piezoelectric material by subjecting the oxide produced in the first step to a hydrothermal processing using an aqueous solution containing the element "a", wherein the amount of the element "a" contained in the piezoelectric material produced in the second step is increased over the amount of the element "a" contained in the oxide produced in the first step.
