ABSTRACT:
In piezoelectric/electrostrictive elements, electrode layers have respective ends projecting outwardly from an end face of a piezoelectric/electrostrictive layer on a side surface where the laminated state of the piezoelectric/electrostrictive layer and the electrode layers is exposed. The distance by which the ends project outwardly from the end face is equal to or smaller than one half of the thickness of the piezoelectric/electrostrictive layer between the electrode layers. The distance is preferably in a range from 0.5 μm to 2 μm.
