Abstract
A liquid ejection head includes a plurality of liquid ejection elements arrayed in a flat area on a substrate. Each liquid ejection element includes a liquid chamber, a heating element disposed in the liquid chamber, and a nozzle. The heating elements are disposed alternately on a first and second lines spaced by δ in a zigzag fashion. Each liquid chamber is formed to have a U-like shape in horizontal cross section such that a wall thereof surrounds three sides of a heating element disposed in each liquid chamber. A gap Wx is formed between each two adjacent liquid chambers located on the second line, and a gap Wy is formed between the liquid chambers located on the first line and the liquid chambers located on the second line. The gaps Wx serve as first common flow channels, and the gap Wy serves as a second common flow channel.
