ABSTRACT:
Provided is a piezoelectric ceramic composition containing a lead titanate which has excellent temperature stability of the resonance frequency, and is suitable for application in a filter, a vibrator or the like, and a piezoelectric element using the piezoelectric ceramic composition. A piezoelectric substrate comprising a ceramic material containing PbTiO.sub.3 is provided with vibrating electrodes on the front and rear surfaces. The ceramic material containing PbTiO.sub.3 contains not less than about 0.1% by weight or more than about 3.0% by weight of Mn based on MnCO.sub.3 as the subcomponent in the main component having a composition satisfying 0.02.ltoreq.x.ltoreq.0.16 and 0.15.ltoreq.y.ltoreq.0.50 of the general formula Pb.sub.1-1.5x Nd.sub.x [(In.sub.1/2 Nb.sub.1/2).sub.y Ti.sub.1-y ]O.sub.3.
