A liquid ejecting head includes a liquid ejecting port for ejecting a liquid and a nozzle layer having a liquid channel communicating with the liquid ejecting port. The nozzle layer has two layers: a first layer at the side of the liquid channel having a resin film formed with an acid and a second layer. The first layer has a smaller static contact angle of water as compared with that of the second layer.

The opening area and shape of ejection orifices provided in an ejection orifice member influence the amount of liquid droplet. Therefore, it is necessary to check the opening area and shape of the ejection orifices in detail. For this purpose, in a liquid ejection head having ejection orifices used for ejecting liquid using energy generated by energy generating elements and a dummy ejection orifice having the same shape as the ejection orifices and not used for ejection of liquid, an examination member is provided at a position facing the dummy ejection orifice.
