<p>PROBLEM TO BE SOLVED: To provide a liquid ejection head and a liquid ejection apparatus that can prevent ejection bending caused by circulation of liquid in a nozzle part.SOLUTION: A liquid ejection head includes: a nozzle part 281 including a nozzle opening 280 through which liquid is ejected, and a nozzle communication channel 220 communicating at one end thereof with the nozzle opening; a pressure chamber communicating with another end of the nozzle communication channel; a piezoelectric element which is provided at the pressure chamber and pressurizes ink in the pressure chamber; a plurality of circulation outlets 226A and 227A which are formed at the nozzle part; a plurality of individual circulation channels 226 and 227 connected with the nozzle part via the respective circulation outlets; and a common circulation channel at which a plurality of connection ports respectively connected with the plurality of individual circulation channels are formed. The nozzle part has a structure where the plurality of circulation outlets are arranged symmetrically with respect to a nozzle axis 281A, and flow rates of liquid, passing through respective circulation outlets when the liquid in the nozzle part is circulated to the common circulation channel, are the same.</p> |
