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) : (PbαLnβMeγ)(Ti1−(x+y+z)ZrxMnyNbz)O3 (1) where Ln is a lanthanoid element, Me is an alkaline-earth metal element, α>0, β>0, γ≧0, 0.965≰α+β+γ≰1.000, 0.158≰x≰0.210, y≧0, z≧0, and 1−(x+y+z)>0.
