Abstract
A liquid ejecting head has head units for ejecting a liquid from nozzles onto a medium that is relatively moved in a first direction are arranged in a second direction perpendicular to the first direction. The head unit includes: a nozzle row in which the nozzles are arranged in a third direction intersecting the first direction and the second direction; a pressure chamber which communicates with the nozzles; a pressure generation element which corresponds to the pressure chamber; a supply liquid chamber which communicates with the pressure chambers and into which the liquid to be supplied to each pressure chamber is introduced; an inflow port through which the liquid flows into the head unit; and an outflow port through which the liquid flows out of the head unit.
