ABSTRACT:
A monolithic piezoelectric body includes first internal electrodes which extend to a first side surface of the piezoelectric body but do not extend to a second side surface of the piezoelectric body, and second internal electrodes which extend to the second side surface but do not extend to the first side surface. A connecting internal electrode is disposed within the piezoelectric body and extends between the first and second side surfaces. A first external electrode is disposed on the first side surface and is electrically connected to the first internal electrodes. A second external electrode is arranged on the first side surface so as to be separated from the first external electrode and electrically connected to the connecting internal electrode. A third external electrode is disposed on the second side surface so as to electrically connect the second internal electrodes and the connecting internal electrode.
