PROBLEM TO BE SOLVED: To provide a droplet ejection head in which torsion of a partition wall part partitioning a pressure generating chamber is suppressed, and defective bonding of a flow channel plate therefore can be prevented.SOLUTION: The droplet ejection head is provided that comprises: a nozzle plate 30 having a plurality of nozzle holes 31 for ejecting droplets; a flow channel plate 20 having a flow channel 25 for supplying liquid to a plurality of pressure generating chambers 22 which are communicated with the plurality of nozzle holes 31, and a partition part 24 which partitions adjacent pressure chambers 22 along a longitudinal direction; a diaphragm 60 which constitutes a wall surface facing the nozzle hole 31, of the pressure generating chamber 22; and pressure generating means 50 for generating a pressure in the pressure generating chamber 22. The droplet ejection head is characterized in that a width of the partition part 24 in a nozzle arrangement direction is wider on a central part side than a longitudinal direction end side.SELECTED DRAWING: Figure 16 |
