Abstract
A liquid ejecting head includes nozzles configured to eject liquid, pressure chambers communicating with the nozzles, the pressure chambers being configured to generate pressure for ejecting the liquid, a first liquid chamber configured to store the liquid to be supplied to the pressure chambers, a second liquid chamber configured to store the liquid that passed through the pressure chambers, first communication paths communicating with the pressure chambers from the first liquid chamber, second communication paths respectively communicating with the second liquid chamber from between the pressure chambers and the nozzles in which flow path resistance in the first communication paths is higher than flow path resistance in the second communication paths.

A liquid ejecting head comprising:
- nozzles configured to eject liquid;
- pressure chambers communicating with the nozzles, the pressure chambers being configured to generate pressure for ejecting the liquid;
- a first liquid chamber configured to store the liquid to be supplied to the pressure chambers;
- a second liquid chamber configured to store the liquid that passed through the pressure chambers;
- first communication paths communicating with the pressure chambers from the first liquid chamber;
- and
- second communication paths respectively communicating with the second liquid chamber from between the pressure chambers and the nozzles, wherein
- a flow path resistance in each first communication path is higher than a flow path resistance in each second communication path, and
- wherein inertance in the second communication path is higher than inertance in the nozzle corresponding to the second communication path.
