摘要： A piezoelectric element contains a piezoelectric ceramic body having a layered perovskite structure, and has the C axis selected and oriented in the thickness direction. In the piezoelectric ceramic body, line shaped electrodes are formed perpendicular to the C axis selected and oriented. The electrodes exposed at both of the end faces of the piezoelectric ceramic body are covered with conductive materials and insulation materials. The piezoelectric ceramic body is polarized in the opposite directions on both of the sides of electrodes arranged in the width direction. Moreover, external electrodes are formed on the faces where the conductive materials and the insulation materials are formed, whereby two groups of the electrodes are arranged in an interdigital electrode form.

摘要： A ceramic composition (sample) includes CaBi4Ti4O15 or another compound having a layered perovskite crystal structures and exhibiting ferroelectricity at ordinary temperature. The ceramic composition (sample) is then heated to a temperature higher than the melting point of the ceramic composition to make the ceramic composition molten or semi-molten. The ceramic composition is then annealed and solidified to yield a grain oriented ceramic (porcelain). This process can produce grain oriented ceramics from ceramic compositions mainly containing a compound having a layered perovskite crystal structure, and can improve electromechanical coefficients of piezoelectric ceramics containing a compound having a layered perovskite crystal structure.
