Abstract
A liquid ejection head includes a substrate in which at least four inlets to which a liquid is supplied are arranged, and an ejection port forming member provided with an ejection port from which the liquid supplied to the inlets is ejected and provided in the substrate. The inlets are each formed along a first direction and are arranged in a second direction which crosses the first direction. A plurality of inter-inlet areas sandwiched between the inlets adjacent to each other has at least two types of areas different in distance between the inlets adjacent to each other, and, among the inter-inlet areas, an area positioned on each of both ends of the substrate is different from an area in which the distance between the inlets is the shortest.
