Abstract

See full text

A piezoelectric layer is integrally formed in such a way that opening portions of a plurality of pressure chambers in a flow channel forming member are covered. In a region that corresponds to a position between adjacent pressure chambers in the piezoelectric layer, a hollow that penetrates the piezoelectric layer or that has a relatively thin thickness in the piezoelectric layer is formed along the sides of the opening of each of the pressure chambers. The hollow is formed to avoid a region along a corner of the pressure chamber in the region.
