Abstract
An inkjet head includes a channel unit and actuator units. Inside the channel unit, individual ink channels are formed so that ink supplied from ink inlets is ejected from nozzles via pressure chambers. The actuator units are bonded to the upper surface of the channel unit. The actuator units have a configuration of four piezoelectric sheets laminated to one another. On the upper surface of the piezoelectric sheet, individual electrodes are disposed in positions opposed to the pressure chambers respectively. A FPC for supplying driving signals to the actuator units is connected to the individual electrodes.
