Abstract:
A liquid ejecting head includes: a first pressure chamber that applies pressure to a liquid; a second pressure chamber that applies pressure to the liquid; a nozzle channel that extends in a first direction and includes a nozzle that ejects the liquid; a first communication channel that extends in a second direction crossing the first direction and enables the first pressure chamber and the nozzle channel to communicate with each other; a second communication channel that extends in the second direction and enables the second pressure chamber and the nozzle channel to communicate with each other; and a first branch channel that has a portion extending in the first direction and enables the first pressure chamber and the nozzle channel to communicate with each other through a path different from a path of the first communication channel.
