    摘要： A ceramic having a plurality of crystal grains that contain lithium and boron, the crystal grains are arranged in a planar direction, and the crystal grains have a mutually same crystal orientation with respect to the thickness direction, the ceramic having a portion defined by parallel sectional surfaces in a thickness direction, the portion being equally divided into a plurality of segments by parallel sectional surfaces in a planar direction, and when the amount of boron in each segment is compared, the thickness of a low boron concentration region, the low boron concentration region being a collection of segments displaying a boron amount of less than or equal to an average value for the maximum value and minimum value of the boron amount, is greater than or equal to 20% to less than or equal to 90% of the overall thickness of the portion.

    摘要： A piezoelectric/electrostrictive element includes a laminated vibrator made of laminations of a piezoelectric/electrostrictive film and an electrode film, with the electrode film having an internal electrode film. The piezoelectric/electrostrictive element has a coating formed on a part of a surface of the laminated vibrator so that the coating selectively and completely covers a defect that would otherwise be exposed on the surface of the vibrator before the coating coats the defect. The defect extends to the internal electrode film and the remainder of the surface of the laminated vibrator is free of the coating.
