发明名称 LIQUID EJECTING HEAD, LIQUID EJECTING HEAD UNIT AND LIQUID EJECTING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a liquid ejecting head in which infiltration of liquid is suppressed, thereby suppressing rupture of an actuator.SOLUTION: The liquid ejecting head includes: a flow path unit 5 in which nozzle orifices and flow paths communicating with the nozzle orifices are provided; a case 4 fixed to the flow path unit; and an actuator unit which is fixed to the case and in which actuators that generate a pressure change in the flow path are juxtaposed, wherein the case is formed of resin molding material, and a reinforcing plate 60 is embedded in the case in the juxtaposition direction of the actuators. A first exposed portion 64 by which the reinforcing plate is exposed is provided on a face on an opposite side to a face of the case fixed to the flow path unit. Concave portions 62 are provided on both side faces of the reinforcing plate in the juxtaposition direction of the actuators on a discharge face side in which the nozzle orifices are opened. A second exposed portions 65 by which corner portions 66 including the discharge face side of convex portions 63 formed by the concave portions 62 and the side faces of the reinforcing plate are exposed are provided on both side faces of the case in the juxtaposition direction of the actuators.
