ABSTRACT:
A Mo side component is added to the essential component of a piezoelectric ceramic composition containing Pb, Zr, Ti and O, in an amount of from about 0.06% by weight to about 5.0% by weight, in terms of MoO.sub.3, relative to the amount of the essential component. Preferably, the side component is added to the calcined essential component, and the resulting mixture is fired to give a sintered piezoelectric ceramic composition. The addition of the side component improves the low-temperature sinterability of the piezoelectric ceramic composition without worsening the piezoelectric characteristics of the composition.
