    摘要: An actuator includes a first electrode disposed on the top surface of a ceramic substrate (for example, zirconium oxide), a piezoelectric/electrostrictive substance disposed on the first electrode, and a second electrode disposed on the piezoelectric/electrostrictive substance, wherein the input of an electric power alters the volume of the piezoelectric/electrostrictive substance. The piezoelectric/electrostrictive substance contains a plurality of crystal grains that have a wavy structure composed of wavy grain boundaries including concave portions and convex portions. The crystal grains contain ABO3 as the main component. The A site is Pb, and the B site contains such an amount of M that M becomes excessive after the piezoelectric/electrostrictive substance is formed (wherein M is at least one element selected from Mg, Ni, and Zn). The crystal grains of the piezoelectric/electrostrictive substance are oriented in the electric field direction, independently of the orientation of the substrate.

    摘要: A crystallographically-oriented ceramic containing Pb and in which piezoelectric/electrostrictive properties can be enhanced. Using a raw material having Pb(Zr1-xTiX)O3 as a main component, a ceramic sheet was formed with a thickness of 15 μm or less. In this material, grains were allowed to grow into an anisotropic shape, and crystal grains with specific crystal planes being aligned were produced. A non-oriented raw material having Pb(Zr1-xTiX)O3 as a main component and the crystal grains were mixed, and shaping was performed so that crystal grains were oriented in a predetermined direction. The shaped body was fired. In the resulting ceramic, the degree of orientation was high at 50% or more. It is possible to enhance the degree of orientation using, as crystal nuclei, a ceramic sheet which can have the same composition as that of the crystallographically-oriented ceramic. Therefore, production can be performed without adding an unnecessary element, for example, for orienting crystals.
