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 49):
A liquid ejection head comprising:\n an ejection opening for ejecting liquid; a pressure chamber having therein an energy generating element for generating energy for ejecting liquid; an ejection opening portion that allows for communication between the ejection opening and the pressure chamber; a first flow passage connected to the pressure chamber and supplying liquid to the pressure chamber; and a second flow passage connected to the pressure chamber and collecting liquid from the pressure chamber, wherein after the liquid flowing into the pressure chamber from the first flow passage reaches a position of a meniscus formed in the ejection opening via the ejection opening portion, the liquid flows into the second flow passage via the ejection opening portion and the pressure chamber in this order.
