Abstract: PURPOSE:To obtain a piezoelectric ceramic having high adhesion strength to electrode and excellent electrical characteristics by adding excess lead monoxide to a mixture of metal compounds having the compositional ratio of lead titanate zirconate, calcining the mixture and heat-treating under reduced pressure. CONSTITUTION:Excess lead monoxide is added to a mixture prepared by compounding metal compounds at ratios to give a compositional ratio of lead titanate zirconate of Pb(formula) (0.5<=X<=0.6).
