Abstract:
1. A liquid ejecting head comprising: a pressure generation chamber to which liquid is supplied through a liquid supply path; a pressure generation unit that generates pressure change in the pressure generation chamber, and a nozzle portion that causes the liquid to be discharged with the pressure generated by the pressure generation unit, wherein the nozzle portion includes: when a cross-sectional area of the liquid supply path in a direction orthogonal to a circulating direction of the liquid is set to Ss, a cross-sectional area of a portion on which the first nozzle portion and the pressure generation chamber communicate with each other is set to Sn, a flow path resistance of the first nozzle portion is set to Rn′, and a flow path resistance of the second nozzle portion is set to Rn, relationships of Sn/Ss≧1/3 and Rn′/Rn≦0.6 are satisfied.
