Abstract
According to one embodiment, an inkjet head includes: a nozzle plate including plural nozzles; a piezoelectric element including plural pressure chambers corresponding to the nozzles and sidewalls provided adjacent to the pressure chambers and serving as driving elements configured to press the pressure chambers to eject liquid from the nozzles; a substrate to which the piezoelectric element is bonded; and a frame member placed on the substrate to surround the piezoelectric element. Grooves are formed on the upper end, and in which an adhesive is applied to bond the upper ends of the sidewalls and the nozzle plate.
