Original Abstract Submitted
A liquid droplet ejecting device includes a channel member and an actuator. The channel member has a channel. The channel includes a nozzle and a pressure chamber communicating with the nozzle. The actuator is on the channel member and configured to apply a pressure to a liquid in the pressure chamber. A diameter of the nozzle and a natural frequency of the channel are parameters of the liquid droplet ejecting device to satisfy that (1) the actuator has a threshold drive frequency of 100 kHz or more, (2) the nozzle ejects a liquid droplet having a volume of 1.8 pl or more, and (3) the Ohnesorge number is 0.2 or more.
