PROBLEM TO BE SOLVED: To provide a droplet discharge head which exhibits excellent discharge stability with a simple structure.SOLUTION: A droplet discharge head includes a nozzle 92 for discharging droplets, a channel plate 100 having a liquid chamber communicating with the nozzle, and pressure generation means which generates a pressure to the liquid chamber. The channel plate includes a plurality of first channel plates 101a having fluid resistance parts communicating with the liquid chamber, and at least one second channel plate 101c which does not have the fluid resistance part, and is structured by alternately laminating the first channel plates and the second channel plate. The first channel plate having the fluid resistance part with minimum fluid resistance out of the fluid resistance parts of the plurality of first channel plates is arranged on a droplet discharge surface side.SELECTED DRAWING: Figure 9 |
