ABSTRACT:
A liquid delivering apparatus, including a flow-passage unit including an opening and a pressure chamber which accommodates liquid and which communicates with the opening; an oscillating plate which partially defines the pressure chamber; a piezoelectric material layer which is one of directly and indirectly stacked on the oscillating plate and which deforms upon application of an electric field thereto so as to oscillate the oscillating plate for delivering the liquid from the pressure chamber through the opening; and an electrode pattern and a drive circuit which apply the electric filed to the piezoelectric material layer. The drive circuit and the electrode pattern are one of directly and indirectly provided on the oscillating plate.
