Abstract
A liquid ejection head includes an ejection opening; a passage in which an energy generation element is disposed; an ejection opening portion that allows communication between the ejection opening and the passage; a supply passage for allowing the liquid to flow into the passage; and an outflow passage for allowing the liquid to flow out to the outside. An expression of H−0.34×P−0.66×W>1.7 is satisfied when a height of the passage is set to H, a length of the ejection opening portion is set to P, and a length of the ejection opening portion is set to W.
