In a piezoelectric ceramic electronic component, internal electrodes 3 are embedded in a piezoelectric ceramic element assembly 1. The piezoelectric ceramic element assembly 1 contains Zr, a lead-free perovskite compound including at least Li and Nb, and a composite oxide including a bivalent metallic element. The molar content of Li and the bivalent metallic element, and the combined molar content thereof are 0.025-0.080 part by mole, 0.045-0.086 part by mole, and 0.076-0.166 part by mole, respectively, with respect to 1 part by mole of Nb. The internal electrodes 3 contain Ni. The piezoelectric ceramic element assembly 1 is obtained by performing calcining synthesis of the perovskite compound, then adding a metallic element compound and a Zr compound thereto and performing calcining synthesis again, and then firing the product. By adjusting the blending ratio of the lead-free piezoelectric ceramic composition, a lead-free piezoelectric ceramic electronic component and a method for manufacturing the same are obtained whereby piezoelectric characteristics can be further enhanced relative to the prior art even when firing is performed together with Ni. |
