摘要： A liquid ejection head includes a plurality of ejection ports, a plurality of pressure chambers each communicating with each of the ejection ports, a piezoelectric actuator constituting part of walls of the pressure chambers, and a common liquid chamber containing liquid to be supplied to the pressure chambers. The pressure chambers and the common liquid chamber are opposed with an opposing wall interposed therebetween. The opposing wall faces the wall of the pressure chambers constituted by the piezoelectric actuator. A reinforcing portion that supports the opposing wall is provided in the common liquid chamber.

摘要： An element substrate includes a discharge port that discharges a liquid, an energy-generating element that generates energy that discharges the liquid from the discharge port, an acting chamber that makes the energy of the energy-generating element act on the liquid, and a heating element including at least two heat generating surfaces that are exposed to the liquid inside the acting chamber, the heating element disposed inside the acting chamber. The element substrate further includes a substrate in which a supply port that supplies liquid to the acting chambers is formed. The heating element may be disposed such that the heat generating surfaces are spaced apart from the substrate.

摘要： An element substrate in which a plurality of members are layered. Plates and a substrate serving as the plurality of members being layered and adhered to each other. The element substrate including a plurality of ejection ports that eject a liquid, and a plurality of supply ports that each communicate with a different ejection port. At least one of the members includes a groove that is, when viewing, from above, a surface in which the ejection ports are formed, formed between two ejection ports, each of which communicates to a different supply port.
