摘要： A ceramic element comprises a main actuator element 26 having an anti-ferroelectric film 22 and a pair of electrodes 24a, 24b formed on a first principal surface (front surface) of the anti-ferroelectric film 22, a vibrating section 18 for supporting the main actuator element 26, and a fixed section 20 for supporting the vibrating section 18 in a vibrating manner. The anti-ferroelectric film 22 after polarization has a region Zt in which its average dielectric constant is increased in an analog manner in accordance with a voltage V applied to the pair of electrodes 24a, 24b. Specifically, an expression of p/t≦2.5 is satisfied provided that an average film thickness of the anti-ferroelectric film 22 is t, and a pitch between the pair of electrodes 24a, 24b is p. Accordingly, the mechanical displacement amount is changed in an analog manner in accordance with the applied voltage, making it possible to maintain a displacement amount equivalent to that obtained during application of a driving voltage, in a no voltage-loaded state after completion of application of the driving voltage.

摘要： An electric-field-inducible deformable porcelain material is provided, comprising a main component BaTiO3, with 0.05 to 2 wt % of at least one selected from Mn, Cu and Co in terms of a metal added thereto. The crystal phase in the porcelain is a single perovskite phase, and the value of the transversal electric-field-inducible deformation is 300×10−6 or more in the field strength of 2000 V/mm. It is presumed that the amount of the rotating 90° domain becomes greater, and the electric-field-induced deformation due to this is increased. Thus, a sufficient displacement amount as a piezoelectric material is obtained.
