A piezoelectric ceramic material composed of a ternary solid solution of Pb(Ni1/3Nb2/3)O3 - PbTiO3 - PbZrO3 having the composition within an area encircled by lines connecting points A(15 mol % of Pb(Ni1/3Nb170 )O3, 45 mol % of PbTiO3 and 40 mol % of PbZrO3), F(40 mol % of Pb(Ni166 Nb2/3)O3, 30 mol % of PbTiO3 and 30 mol % of PbZrO3), C(51 mol % of Pb(Ni1/3Nb2/3)O3, 24 mol % of PbTiO3 and 25 mol % of PbZrO3), G(45 mol % of Pb(Ni1/3Nb2/3)O3, 35 mol % of PbTiO3 and 20 mol % of PbZrO3), H(40 mol % of Pb(Ni1/3Nb170 )O3, 40 mol % of PbTiO3, and 20 mol % of PbZrO3) and I(30 mol % of Pb(Ni1/3Nb2/3)O3, 45 mol % of PbTiO3 and 25 mol % PbZrO3). And at least one additive selected from the group consisting of Sb2O3, Nb2O5, Bi2O3, La2O3, WO3 is added to the ternary solid solution in an amount of 0.1 to 1.0 weight % of the ternary solid solution.
