Abstract:
1. A liquid droplet jetting apparatus which jets a droplet of a liquid, comprising: a channel unit which includes a plurality of nozzles, a plurality of pressure chambers arranged in a predetermined plane, a partition wall partitioning the pressure chambers, a plurality of common liquid chambers supplying the liquid to the pressure chambers, a plurality of liquid channels communicating the nozzles, the pressure chambers and the common liquid chambers, and a communicating channel communicating the common liquid chambers; and a pressure applying mechanism which applies selectively a jetting pressure to the liquid in the pressure chambers, wherein the communicating channel is formed in the channel unit, at a position which overlaps with the partition wall in an orthogonal direction which is orthogonal to a planar direction of the predetermined plane, and which is different from the pressure chamber in the orthogonal direction.
