摘要（英）：

The invention provides a piezoelectric ceramic composition, a piezoelectric element and a resonator. The piezoelectric ceramic composition can increase Qmax of a resonator and inhibit the resonator from changing its oscillation frequency F0 under a low temperature environment. The piezoelectric ceramic composition has a structure represented by the following general formula (1): (Pb[alpha]Ln[beta]Me[gamma])(Ti1-(x+y+z)ZrxMnyNbz)O3 (1) where Ln is a lanthanoid element, Me is an alkaline-earth metal element, [alpha]>0, [beta]>0, [gamma]>=0, 0.965!<=[alpha]+[beta]+[gamma]!<=1.000, 0.158!<=x!<=0.210, y>=0, z>=0, and 1-(x+y+z)>0.
