Abstract
An element body having a first and second internal electrodes exposure surface comprising a piezoelectric active area, wherein a first internal electrode faces a second internal electrode sandwiching piezoelectric body layer in-between along laminating direction, and a piezoelectric inactive area, wherein the piezoelectric body layer contacts only first or second internal electrode at one face along laminating direction, or the first internal electrodes or the second internal electrodes respectively face each other sandwiching piezoelectric body layer in-between along laminating direction, an insulating layer which covers the piezoelectric active area of the first and second internal electrodes exposure surface, and a resistance layer which is isolated from the piezoelectric active area by the insulating layer, placed at the first and second internal electrodes exposure surface connecting at least a part of the first and that of the second internal electrode in the piezoelectric inactive area and has lower electrical resistance value relative to that of the piezoelectric body layer.
