摘要：A liquid discharge device () has a pressure chamber (), a nozzle (), and acommunication path () that interconnects the pressure chamber () and the nozzle (). Aregion that has a specific length Land lies from the position () of the boundary betweenthe communication path () of the pressure chamber () toward the nozzle () is formed as a

narrow section () that has an opening area Ssmaller than the opening area Sof a regioncloser to the nozzle () than the narrow section (). In the liquid discharge device (), thenarrow section () functions to damp micro vibration that occurs in liquid in the

communication path (), and this allows liquid drops having a pre-designed volume andflying speed to be discharged from every nozzle () on a board ()
