ABSTRACT:
The liquid ejection head comprises: a pressure chamber which is connected to an ejection port ejecting liquid; an actuator which is disposed inside the pressure chamber and deforms due to prescribed driving; a holding member which holds the actuator; and a shielding member which, when a surface of the actuator held by the holding member is a bottom face, seals off the liquid inside the pressure chamber from side faces of the actuator, while allowing an upper surface of the actuator to make contact with the liquid inside the pressure chamber.
