<P>PROBLEM TO BE SOLVED: To provide a liquid ejection head capable of alleviating crosstalk without attenuating energy (vibration) necessary for ejection, and an inkjet recorder having the same. <P>SOLUTION: This liquid ejection head 10 has a plurality of ejectors each of which is constituted by a nozzle 12 for ejecting liquid droplets, a pressure chamber 14 provided corresponding to the nozzle 12 and an energy generation element 16 for applying an ejection force to liquid in the pressure chamber 14. The liquid ejection head 10 includes common fluid channels 20, 30 for supplying liquid to the plurality of pressure chambers 14, constriction sections provided at discrete fluid channel portions 22, 32 connecting the respective pressure chambers 14 to the common fluid channels 20, 30, and atmospheric air opening holes 24, 34 which communicate with the common fluid channels 20, 30 and have openings at a nozzle face 11. Fluid vibration is absorbed by vibration of meniscuses in the atmospheric air opening holes 24, 34. <P>COPYRIGHT: (C)2012,JPO&INPIT |
