摘要：
A liquid droplet discharge apparatus, which discharges liquid droplets of a liquid, includes: a flow passage unit which is formed with a plurality of nozzles for discharging the liquid droplets of the liquid and a plurality of liquid flow passages including a plurality of pressure chambers communicated with the plurality of nozzles respectively; an actuator which has a sealing plate joined to the flow passage unit for defining the plurality of pressure chambers and which applies a pressure to the liquid contained in each of the plurality of pressure chambers by changing a volume of each of the plurality of pressure chambers by deforming the sealing plate; and a deformation adjusting member which adjusts a deformation amount of the sealing plate.
