Document Type and Number:
Japanese Patent JP3991564
Kind Code:
B2
Abstract:
A piezoelectric ceramic composition and a piezoelectric element in which cracks and chips are not likely to occur during working even if the thicknesses are reduced, are provided. The piezoelectric ceramic composition contains as a primary component, a complex oxide having a perovskite structure, composed of at least Pb, Zr, Ti, Mn, Nb and O, and represented by general formula ABO3, in which the total molar quantity of elements constituting A is smaller than the total molar quantity of elements constituting B, and Si is present as a secondary component at the content of about 0.010 wt % to 0.090 wt %, in terms of SiO2, relative to the primary component.
