  • Patent number: 11331916
    Abstract: A liquid ejecting head including a flow path forming substrate in which a pressure chamber is formed, a diaphragm, and a piezoelectric actuator. The piezoelectric actuator includes an active portion in which a piezoelectric layer is interposed between a first electrode and a second electrode. The active portion, in plan view, overlaps at least a portion of the pressure chamber and is provided so as to extend to an outside of the pressure chamber. The pressure chamber is formed so that, the closer to the piezoelectric actuator in a layered direction of the flow path forming substrate and the diaphragm, a width of the pressure chamber in a direction intersecting the layered direction becomes smaller.
