Patent ID: 8632165

Claim:
A liquid-ejecting head comprising: a channel that is in communication with a nozzle opening that serves for liquid ejection, the channel including a pressure-generating chamber; a circulation channel that serves to circulate a liquid in the channel; and a pressure generator that serves to generate pressure change in a liquid in the pressure-generating chamber, wherein the circulation channel has a narrow portion including a first wall and a second wall, the first wall tilting with respect to a forward direction in which a liquid flows and serving to gradually decrease the cross-sectional area of the circulation channel toward the downstream side in the forward direction, the second wall tilting with respect to the flow direction and serving to gradually increase the cross-sectional area that has been gradually decreased by the first wall, wherein the tilt angle of the first wall with respect to the inner surface of the circulation channel at the upstream side relative to the first wall is larger than the tilt angle of the second wall with respect to the inner surface of the circulation channel at the downstream side relative to the second wall.
