    摘要: An object of the present invention is to provide a stacked piezoelectric element with excellent durability, which exhibits an excellent piezoelectric performance irrespective of containing or not containing Pb in the ceramic layer, ensures sufficiently suppressed segregation of the electrically conducting base metal material in the ceramic layer and allows for no segregation of a strengthening substance itself. A stacked piezoelectric element obtained by alternately stacking a piezoelectric ceramic layer and an electrode layer, wherein said electrode layer mainly comprises an electrically conducting base metal electrode material, and the region held between the electrode layer positioned at the top of each ceramic layer and the electrode layer positioned at the bottom of each ceramic layer contains a material having no piezoelectricity, in which a constituent element of said material having no piezoelectricity is uniformly dispersed so as not to have local distribution of a distributed strength exceeding 2 times the distributed strength which is distributed in a largest number of places and is not 0.
