A liquid ejecting head that has substrates stacked in a first direction, the liquid ejecting head comprising:
- individual flow paths respectively communicating with nozzles configured to eject liquid in the first direction;
- a supply common liquid chamber that extends in a direction intersecting the first direction and communicates with the individual flow paths to supply liquid to the individual flow paths;
- a discharge common liquid chamber that extends in a direction intersecting the first direction and communicates with the individual flow paths and through which liquid discharged from the individual flow paths flows;
- and
- a bypass flow path coupling the supply common liquid chamber to the discharge common liquid chamber, wherein
- the supply common liquid chamber and the discharge common liquid chamber are formed in the same layer among the substrates, and
- the bypass flow path has a first portion formed in a layer different from the supply common liquid chamber and the discharge common liquid chamber, among the substrates.
