    摘要: A piezoelectric element structure comprises a supporting substrate, and a piezoelectric film supported on the supporting substrate, in which the piezoelectric film contains a first layer, and a second layer having zirconium, each provided with perovskite structure, and formed to be in contact with each other or laminated through an intermediate layer, and the temperature is set at 500° C. or more at the time of thin film formation so as to provide the piezoelectric film, and a quick cooling is given from the thin film formation temperature at least to 450° C. with a cooling speed of 30° C./min or more for the formation thereof. The piezoelectric film thus formed is in a small thickness as compared with the conventional piezo-electric film, but presents a large piezoelectric constant, hence making it possible to perform efficient microprocessing thereof reliably.

    摘要: A dielectric element includes a lower electrode layer provided on a substrate, a dielectric layer provided on the lower electrode layer and an upper electrode layer provided on the dielectric layer. The dielectric layer has a first dielectric layer provided on a side of the lower electrode layer, and a second dielectric layer provided on a side of the upper electrode layer. The second dielectric layer is a layer comprised mainly of an oxide including four or more kinds of metal element components, and the first dielectric layer does not substantially include at least one component selected from metal elements included in the oxide layer of the second dielectric layer and is comprised mainly of an oxide including at least three components selected from the remaining metal elements without substantially including Ti and Zr elements.
