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 31):
A liquid ejection head comprising:\n an ejection opening for ejecting a liquid; a pressure chamber having therein an energy generation element for generating energy for ejecting the liquid; an ejection opening portion that allows communication between the ejection opening and the pressure chamber; a first flow passage connected to the pressure chamber and supplying the liquid to the pressure chamber; and a second flow passage connected to the pressure chamber and collecting the liquid from the pressure chamber, wherein an expression of H \u22120.34 \u00d7P \u22120.66 \u00d7W>1.7 is satisfied when the height of the pressure chamber on the first flow passage side is set to H [\u03bcm], a length of the ejection opening portion in a direction in which the liquid is ejected from the ejection opening is set to P [\u03bcm], and a length of the ejection opening portion in a flow direction of the liquid inside the pressure chamber is set to W [\u03bcm].
