Abstract
According to one embodiment, a method for manufacturing an inkjet head includes attaching a piezoelectric body facing the substrate, forming slanting side surfaces on the piezoelectric body, the slanting side surfaces extending between a first surface and a second surface of the piezoelectric body such that first surface has a remaining area that is less that a remaining area of second surface, forming a groove in the piezoelectric body from the first surface towards the second surface, the groove passing through two slanting side surfaces on opposite sides of the piezoelectric body, forming a conductive film on an inner surface of the groove, trimming portions of the conductive film proximate to the first surface and the slanting side surfaces such that the conductive film is separated from the first surface and the slanting side surfaces at outer edges of the groove, and forming an insulating film over the conductive film.
