摘要： 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.
