Original Abstract Submitted
An object is to provide a liquid ejection head thinner than ones in the prior art 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 being located above the first downstream flow channel vertically and being where a sectional area of the first upstream flow channel becomes smaller and smaller downwards vertically. The second upstream flow channel has a second region being located above the second downstream flow channel vertically and being where a sectional area of the second upstream flow channel becomes smaller and smaller downwards vertically. In a view seen 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.
