Abstract
According to one embodiment, an inkjet head includes a nozzle plate, a piezoelectric member, a substrate, a frame member, and a wiring circuit. The nozzle plate has nozzles. The piezoelectric member has pressure chambers associated with the nozzles, sidewalls configured to pressurize the pressure chambers, and electrode wiring lines that are connected to electrodes provided on the respective sidewalls and alternately provided on one of both end sides of each of the pressure chambers which is different from the end side of respective adjacent pressure chambers. Further, the piezoelectric member applies a drive pulse voltage to the sidewalls from the electrodes to pressurize the pressure chambers. The piezoelectric member is bonded to the substrate. The frame member is bonded to the substrate and the nozzle plate to surround the piezoelectric member. The wiring circuit is provided on the substrate and has the electrode wiring lines.
