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.

摘要： A liquid ejection head includes a member having ejection ports and dummy ejection ports. The ejection ports are provided in correspondence with energy-generating elements used in ejecting liquid. The dummy ejection ports are provided in correspondence with a light-receiving element outputting current whose level changes in accordance with the intensity of light applied thereto. By detecting the level of current that is output from the light-receiving element, the shapes of the ejection ports are estimated.
