Patent ID: 8567914

Claim:
A liquid ejecting head that ejects a liquid from a common liquid chamber that is common for a plurality of pressure chambers, supply channels for each of the pressure chambers that communicate between the pressure chambers and the common liquid chamber, through nozzles that communicate with the pressure chambers by imparting a pressure fluctuation on the pressure chambers, wherein when the inertance of the nozzles is represented by Mn, the inertance of the supply channels is represented by Ms, the combined resistance obtained by combining the flow channel resistance in the nozzles, the flow channel resistance in the pressure chambers, and the flow channel resistance in the supply channels is represented by R, and a unique vibration cycle of the pressure fluctuation arising in the liquid within the pressure chamber is represented by Tc, the following Equation (A) holds true √{square root over (MnMs)}≦RTc (A).
