    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： BaTiO3—PbTiO3 series single crystal is single-crystallized by heating BaTiO3—PbTiO3 compact powder member or sintered member having a smaller Pb-containing mol number than Ba-containing mol number, while keeping the powder or substance in non-molten condition. In this way, this single crystal can be manufactured at a crystal growing speed faster still and stabilized more, significantly contributing to improving the dielectric loss and electromechanical coupling coefficient for the provision of excellent BaTiO3—PbTiO3 series single crystal in various properties, as well as for the provision of piezoelectric material having a small ratio of lead content, which is particularly excellent in piezoelectric property and productivity.
