ABSTRACT:
Pairs of laminated piezoelectric actuator (111) are arranged in plural rows on a base plate (110) to form a laminated piezoelectric actuator unit. A diaphragm (115) is bonded to the upper end surface of the laminated piezoelectric actuator unit, and a flow path plate (118) is bonded to the upper surface of the diaphragm (115). Here, a plurality of pressurizing chambers (116) and an ink flow path (117) are formed in the flow path plate (118) such that each pressurizing chamber (116) is disposed corresponding to each laminated piezoelectric actuator (111). Moreover, a nozzle plate (120) having nozzle holes (119) is connected to the upper surface of the flow path plate (118). Each laminated piezoelectric actuator (111) is deformed in the direction of thickness by applying voltage thereto for ejecting ink inside each pressurizing chamber (116) via each nozzle hole (119) in a direction perpendicular to the base plate (110).
