A liquid ejection head includes a plurality of liquid ejection units, each including a plate-like piezoelectric element, a first substrate and a second substrate laid one on the other in this order, the units being laid one on the other. The first substrate defines a plurality of pressure chambers for storing liquid, each of the pressure chambers communicating with an ejection port for ejecting liquid. At least either the first substrate or the second substrate defines a first liquid chamber, the first liquid chamber being either one of a feed chamber for feeding liquid to the pressure chambers and a recovery chamber for recovering liquid from the pressure chambers. The second substrate defines a second liquid chamber, the second liquid chamber being the other one of the feed chamber and the recovery chamber.
