A liquid ejecting head comprising:
- a first pressure chamber that extends in a first direction and applies pressure to a liquid;
- a second pressure chamber that extends in the first direction and applies pressure to the liquid;
- a nozzle channel that communicates with a nozzle for ejecting the liquid;
- a first communication channel that extends in a second direction orthogonal to the first direction and enables the first pressure chamber and the nozzle channel to communicate with each other;
- and
- 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, wherein
- the nozzle channel includes
- a first portion that extends in the first direction and communicates with the first communication channel and
- a second portion that extends in a third direction crossing the first direction and orthogonal to the second direction and communicates with the first portion, and
- an angle formed between the first direction and the third direction is larger than 0° and smaller than 90°.
