Abstract
A liquid ejection head can be formed to be thinner than previous designs even in a case where multiple flow channels are arranged. In a state where the liquid ejection head is in use, a first upstream flow channel has a first region located above a first downstream flow channel vertically and a sectional area of the first upstream flow channel decreases downwards vertically. A second upstream flow channel has a second region located above a second downstream flow channel vertically and a sectional area of the second upstream flow channel decreases downwards vertically. As viewed in the first direction, the first downstream flow channel and the second downstream flow channel do not overlap with each other, while the first region and the second region overlap with each other.
