Abstract
A multilayer ceramic structure, which is to be divided into a large number of piezoelectric actuators, includes a rectangular-parallelepiped-shaped multilayer ceramic body. An upper surface opposing electrode is formed on an upper surface, a lower surface opposing electrode is formed on a lower surface and inner opposing electrodes are formed inside the multilayer ceramic body. A silt is provided in the upper surface opposing electrode. Opposing portions are provided where the upper surface opposing electrode, the inner opposing electrodes and the lower surface opposing electrode are superposed with each other when viewed in plan. The slit is provided in the upper surface opposing electrode in a portion of a region between the opposing portion and the first side surface and so as to extend in a first direction linking a first end surface and a second end surface.
