The substrate has, above one side thereof, an energy generating element configured to generate energy used to eject liquid. The ejection port, from which a liquid is ejected, is located at a position corresponding to the energy generating element. The liquid channel communicates with the ejection port and penetrates the substrate from the one side to another side of the substrate. The supply port communicates with the liquid channel. The substrate has a projecting layer extending inward of an inner peripheral portion of an opening in the supply port in the one side, and the projecting layer and the energy generating element are formed of the same material.
