An inkjet head includes an actuator unit, and a flow path unit. Individual electrodes are formed on a piezoelectric sheet of the actuator unit. Pressure chambers are formed in a cavity plate of the flow path unit. Each individual electrode has a main electrode region disposed in a position opposite to a corresponding pressure chamber, and a land portion connected to the main electrode region. Overhang portions protruding in a direction along a surface of the cavity plate are formed in side walls of each pressure chamber. Each land portion at least partially overlaps a corresponding overhang portion at a height level (top height level) of a contact surface between the cavity plate and the actuator unit. <IMAGE> |
