Piezoelectric element, droplet-ejecting head, droplet-ejecting apparatus, and method of producing a piezoelectric element
Abstract:
The present invention provides a piezoelectric element including a piezoelectric body and top and bottom electrodes holding the piezoelectric body therebetween, wherein an interlayer dielectric having an opening that defines an active area of the piezoelectric body is interposed between the piezoelectric body and the top electrode, and the top electrode is layered directly on the piezoelectric body in the active area of the piezoelectric body.
Abstract(Chinese):

本发明提供一种压电元件，包括压电体和将压电体保持在其间的顶部和底部电极，其中具有限定压电体的有效面积的开口的层间电介质介于压电体和顶部电极之间，并且 在压电体的有源区域中，顶部电极直接层压在压电体上。
