Abstract: A liquid discharge device is used that includes: a nozzle having a first holding part and a second holding part and for discharging a liquid droplet; a base to which the nozzle is attached; a fixing part for fixing the nozzle to the base; and a drive part that creates displacement in the nozzle. The drive part holds at least one of the first holding part and the second holding part. Whichever of the first holding part and the second holding part that is not held by the drive part is held by the fixing part.

Abstract: In a common chamber (102) for distributing, to respective pressure chambers (211), an ink supplied from the ink inlet (101), resistant walls (111) are provided in areas that are located ahead and behind of the flow of the ink, i.e., areas around inlets of flow channels (221) that lead to respective pressure chambers (211), and any resistance against the flow of the ink is generated according to the heights of the resistant walls (111), thereby capturing a solid ingredient (150) included in the ink. In this case, by adjusting the heights of the resistant walls (111) to control capabilities of introducing the solid ingredient (150), it becomes possible to dispense desired amounts of the solid ingredient (150) to the respective pressure chamber (211).
