An inkjet recording head includes a two-dimensional array of a pressure chambers
and corresponding array of piezoelectric elements each for applying a pressure
wave to ink in a corresponding pressure chamber. In fabrication, a piezoelectric
plate temporarily bonded onto a substrate is subjected to sandblasting to form
the plurality of piezoelectric elements After the piezoelectric elements are bonded
as a unit onto a diaphragm which constitutes part of the walls of the pressure
chambers, the substrate is removed. Dummy patterns equalize the degree of side
etching among the piezoelectric elements.
