摘要： A liquid-ejecting head includes a channel which is in communication with a nozzle opening and which includes 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. 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 of a liquid flows and serving to gradually decrease the cross-sectional area, the second wall tilting with respect to the flow direction and serving to gradually increase the cross-sectional area. The tilt angle of the first wall with respect to the inner surface of the circulation channel is larger than the tilt angle of the second wall with respect to the inner surface of the circulation channel at the downstream side.

摘要： A liquid ejecting head of the present invention has a nozzle plate including a nozzle substrate composed of a non-conductive material in which nozzle openings pass through the nozzle substrate and a conductive film formed to cover at least a part of the inner peripheral wall surface of the nozzle opening. The film forming area where the conductive film is formed includes the moving range of a meniscus moving on the inner peripheral wall surface of the nozzle opening in accordance with the ejection operation of liquid drops from the nozzle opening. According to the present invention, even if a non-conductive nozzle plate is used, a charge can be injected smoothly into liquid drops without causing problems of deterioration of the image quality due to electrophoresis and of defective ejection due to foreign substances and gas generated by electrolysis.
