Abstract
A stacked piezoelectric ceramic component (10) includes a stacked body (20) which includes a plurality of electrodes (12, 13) and piezoelectric ceramic layers (11) stacked such that each of the electrodes (12, 13) is disposed between the piezoelectric ceramic layers, the piezoelectric ceramic layers containing alkali niobate-based perovskite-type oxide as a main component. In the stacked piezoelectric ceramic component (10), a portion of the piezoelectric ceramic layers (11), which portion is not sandwiched between the plurality of stacked electrodes (12, 13) serves as a non-active layer (21). The non-active layer (21) has a thickness of 25 μm or greater.
