Provided is a piezoelectric ceramic composition which 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): (PbαLn&bgr;Meγ)(Ti1−(x+y+z)ZrxMnyNbz)O3  (1) where Ln is a lanthanoid element, Me is an alkaline-earth metal element, α>0, &bgr;>0, γ≧0, 0.965≦̸α+&bgr;+γ≦̸1.000, 0.158≦̸x≦̸0.210, y≧0, z≧0, and 1−(x+y+z)>0. |
