description A liquid ejection head includes a substrate including an energy generating element configured to generate energy used for ejecting a liquid, a flow channel member overlying the substrate and defining a flow channel through which a liquid is supplied, and an ejection opening member overlying the flow channel member and defining an ejection opening through which the liquid supplied through the flow channel is ejected by the energy from the energy generating element. The flow channel member contains a crosslinked cured product of a multifunctional epoxy resin and a polyhydric alcohol having a perfluoroalkyl group in the molecular structure, and the concentration of a component derived from the polyhydric alcohol in the flow channel member is lower on the side adjacent to the substrate than on the side adjacent to the ejection opening member.
