Patent ID: 8205978

Claim:
A liquid ejecting head for ejecting a liquid from a plurality of ejection holes, comprising: a first flow-passage member in which are formed (a) a liquid-supply passage to which the liquid is supplied from an exterior of the liquid ejecting head, (b) a plurality of branch passages connected to the liquid-supply passage, and (c) a plurality of discharge passages each of which is connected to any of the plurality of branch passages and each of which is in communication with an outside of the first flow-passage member; a second flow-passage member in which are formed (a) at least one common liquid passage each of which is in communication with at least one of the plurality of branch passages and (b) a plurality of individual passages which are provided so as to respectively correspond to the plurality of ejection holes, each of which is connected to any one of the at least one common liquid passage, and which respectively have pressure chambers formed therein, each of the plurality of individual liquid passages introducing the liquid to a corresponding one of the plurality of ejection holes via a corresponding one of the pressure chambers; a first filter disposed in the liquid-supply passage; a plurality of second filters disposed between the plurality of branch passages and the at least one common liquid passage; and at least one energy giving member configured to give ejection energy to the liquid in each of the pressure chambers that are formed respectively in the plurality of individual liquid passages, wherein each of the plurality of discharge passages is connected to one of the plurality of branch passages at a downstream side of the first filter.
