Summary:PROBLEM TO BE SOLVED: To provide a printing apparatus capable of ejecting minute droplets with a high position accuracy.SOLUTION: A printing apparatus includes: a flow channel plate 110 including a nozzle 128 including an outlet, through which ink contained in a pressure chamber 125 is ejected, and a trench located around the nozzle 128 and opened in the same direction as the outlet so that the outlet extends into the opening; a piezoelectric actuator 130 configured to provide a change in pressure to eject the ink contained in the pressure chamber 125; and an electrostatic actuator 140 configured to provide an electrostatic driving force to the ink contained in the nozzle 128.SELECTED DRAWING: Figure 1 【課題】微細液滴を高度な位置精度で吐出することができるプリンティング装置を提供する。【解決手段】プリンティング装置は、圧力チャンバ１２５内のインクが吐出される出口を含むノズル１２８と、該ノズル１２８周囲に位置し、該出口と同じ向きに開口され、該出口が開口内部に延びているトレンチとを含む流路プレート１１０と、圧力チャンバ１２５内のインクに、吐出のための圧力変化を提供する圧電アクチュエータ１３０と、ノズル１２８内のインクに静電駆動力を提供する静電アクチュエータ１４０とで構成されている。【選択図】図１
