Abstract
A piezoelectric device including an insulating substrate and a displacement layer formed on the insulating substrate including a first common electrode, a piezoelectric layer and a plurality of second electrodes laid on the insulating substrate in the stated order, where a part of a surface of the piezoelectric device in a region where the first and the second electrodes overlap each other is projected out of the rest part of the surface. The thus-formed piezoelectric device can increase the amount of displacement of the displacement layer.
