Abstract
A liquid ejection head includes a nozzle plate where a nozzle for ejecting a liquid is provided, a substrate including a piezoelectric element for generating pressure for ejecting the liquid from the nozzle, and a wall member made of a resin and provided between the nozzle plate and the substrate to form a pressure chamber that communicates with the nozzle. A structure for connecting at least two side surfaces, among a plurality of side surfaces of the wall member that forms the pressure chamber, is provided.

A liquid ejection head comprising:
- a nozzle plate where a nozzle for ejecting a liquid is provided;
- a substrate including a piezoelectric element for generating pressure for ejecting the liquid from the nozzle;
- and
- a wall member made of a resin and provided between the nozzle plate and the substrate to form a pressure chamber that communicates with the nozzle,
- wherein a structure for connecting at least two side surfaces, among a plurality of side surfaces of the wall member that forms the pressure chamber, is provided,
- wherein the liquid ejection head includes a plurality of the nozzles and a plurality of the pressure chambers each having a cuboid shape and respectively corresponding to the plurality of nozzles, and
- wherein the liquid ejection head satisfies a relationship T/L>2, where L is a thickness of the wall member between the plurality of pressure chambers adjacent to each other in a short side direction of the plurality of pressure chambers and T is a height of the plurality of pressure chambers in a direction perpendicular to the substrate.
