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.
