Abstract:
1. A liquid-ejecting head comprising: pressure-generating chambers, each of which is in communication with a nozzle opening that serves for liquid ejection; ink-supplying channels, each of which is in communication with one of the pressure-generating chambers; circulation communication channels, each of which is in communication with one of the pressure-generating chambers; a common liquid chamber which is in communication with the ink-supplying channels; a circulation channel which is in communication with the circulation communication channels; pressure generators, each of which serves to generate pressure change in a liquid in the pressure-generating chamber, wherein the circulation channel which serves to circulate the liquid supplied from the common liquid chamber through the circulation communication channels, channel resistance of the liquid flowing in the circulation communication channel from the common liquid chamber to the circulation channel is smaller than that from the circulation channel to the common liquid chamber.
