Abstract
A liquid ejection head includes an element substrate and a support member. The element substrate includes an ejection orifice row, and a supply port. The support member includes a first flow path for supplying a liquid from a liquid supply source to the supply port. The first flow path includes a plurality of channels for supplying liquid to the supply port. At least one of the plurality of channels has a shape in which a cross section that intersects with a flow direction Y of the liquid increases from an upstream side to a downstream side with respect to the direction in which the liquid is supplied.
