Abstract: A liquid ejection head includes a liquid path; an ejection outlet forming member which constitutes a part of a wall of the liquid and which forms an ejection outlet for ejecting a droplet of liquid; a heat generating element, provided at a position opposing to the ejection outlet of the wall of the liquid flow path, for generating a bubble in the liquid by application of heat to the liquid; a restrictor portion, provided at a recessed portion of the ejection outlet, wherein the recessed portion is recessed from a plane in which the ejection outlet is formed, wherein the liquid forms a meniscus and is retained in the ejection outlet such that the restrictor portion is within the liquid, wherein an area So of an opening of the restrictor portion and a surface Sh of the heat generating element satisfy So ~ Sh. According to this invention, a central portion of the meniscus opposed to the fine opening at the ejection outlet bulges, and the liquid is ejected in this state. Namely, very small amount of the liquid can be ejected, since not all of the liquid in the recess portion in the ejection outlet is ejected.
