Abstract:
A liquid ejection head includes first individual channels arranged in a first direction, a first common channel extending in the first direction and communicating with the first individual channels, and a second common channel located below the first common channel and extending in the first direction. The second common channel communicates with the first individual channels. Each of the first individual channels includes one of first nozzles, and one of first pressure chambers that communicate with the respective first nozzles and are located above the first nozzles. The first common channel and the second common channel overlap, in a vertical direction, with each other at a position above the first pressure chambers. The first common channel overlaps, in the vertical direction, with the first pressure chambers. The second common channel does not overlap, in the vertical direction, with the first pressure chambers.
