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.

Claim (Index 32):
The liquid ejection head according to  claim 31 , further comprising:\n an orifice plate on which the ejection opening and the ejection opening portion are formed; and a substrate on which the energy generating element is formed, wherein between the orifice plate and the substrate, the pressure chamber, the first flow passage, and the second flow passage are formed.
