A laminated piezoelectric element includes a second connecting internal electrode electrically connected to a common external electrode that is located in a bottom portion, which lies below the bottoms of slits, of a monolithic piezoelectric body, and the second connecting internal electrode is spaced away from and substantially parallel to the first and second driving internal electrodes. In the laminated piezoelectric element, a notch is formed on a side surface of the monolithic piezoelectric body, having a driving external electrode and a connecting external electrode disposed thereon, and a conducting external electrode is disposed on the side surface of the notch, having an end of the second internal electrode exposed thereat.
