A multilayer sintered body (1) is obtained by alternately laminating internal electrodes (3) mainly composed of Ni and piezoelectric ceramic layers and sintering the laminate. The piezoelectric ceramic layers contain, as a main component, a perovskite compound containing Nb, K, Na and Li, while containing at least one element M1 selected from among Nd and Dy and at least one element M2 selected from among Ga and Al. If dissolved through a dissolution treatment, the content of the element M2 is 0.071 part by mole or less relative to 1 mole of Nb. This multilayer piezoelectric ceramic electronic component is produced by co-firing conductive films, which form the internal electrodes (3), and ceramic green sheets, which form the piezoelectric ceramic layers, in a reducing atmosphere that suppresses oxidation of Ni. Consequently, a highly reliable multilayer piezoelectric ceramic electronic component and a method for manufacturing the multilayer piezoelectric ceramic electronic component are achieved. |
