Abstract
A multilayer sintered body having alternately stacked Ni-based inner electrodes and piezoelectric ceramic layers. The piezoelectric ceramic layers contain a main ingredient of a perovskite compound containing Nb, K, Na, and Li, at least one element M1 selected from Nd and Dy, and at least one element M2 selected from Ga and Al. The element M2 content is 0.071 parts by mole or less per 1 part by mole of the Nb in a solution obtained through a dissolution process. This multilayer piezoelectric ceramic electronic component is manufactured through the cofiring of conductive films as a precursor of the inner electrodes and ceramic green sheets as a precursor of the piezoelectric ceramic layers in a reducing atmosphere in which the oxidation of Ni is inhibited.
