Abstract:
1. A perovskite type oxide represented by ABO 3 , wherein site A includes Pb as a main component and site B includes a plurality of elements, and wherein the perovskite type oxide has a crystal structure that is one of (a) a crystal structure including a plurality of crystal phases selected from the group consisting of tetragonal, rhombohedral, orthorhombic, cubic, pseudo-cubic and monoclinic structures, the plurality of crystal phases being oriented in the <100>direction and having no crystal grain boundaries interposed between the plurality of crystal phases, and (b) a crystal structure having no crystal grain boundaries in a direction of the oriented axis and having crystal grains respectively including a plurality of crystal phases selected from the group consisting of tetragonal, rhombohedral, orthorhombic, cubic, pseudo-cubic and monoclinic structures, the plurality of crystal phases being oriented in the <100>direction, the crystal grains respectively having no grain boundaries interposed between the plurality of crystal phases.
