A liquid ejecting head includes: a pressure generating chamber to which liquid is supplied through a liquid supply channel; a pressure generating unit that generates a variation in pressure in the pressure generating chamber; a nozzle opening that ejects the liquid discharged from the pressure generating chamber according to the variation in pressure to the outside; and a flow channel for circulation that is formed in the nozzle opening side rather than the pressure generating chamber and separates a part of the liquid discharged from the pressure generating chamber. When Ms, Mn, and Mc each are inertances of the liquid supply channel, the nozzle opening, and the flow channel for circulation, a relationship of Ms≧(1/Mn+1/Mc)−1 is established. |
