ABSTRACT:
A multi-layered piezoelectric device includes a plurality of piezoelectric portions and a plurality of electrodes electrically connected to the piezoelectric portions that are formed in layers on a ceramic substrate. A first piezoelectric portion is made of a piezoelectric ceramic composition containing Ni in an amount of 0.08 to 0.31% by mass (in terms of NiO), and second and upper piezoelectric portions are made of a piezoelectric ceramic composition of higher Ni content than in the first piezoelectric portion. An electrode is provided at least between the first piezoelectric portion and the second piezoelectric portion.
