Zusammenfassung:	To satisfactorily maintain a ground state of a liquid discharge head.SOLUTION: A liquid discharge head 202 includes: nozzle formation members formed with nozzles for discharging a liquid; opening/closing members for opening/closing the nozzles; piezoelectric bodies 9 expanding and contracting in an axial direction by a driving voltage, and actuating the opening/closing members so as to open/close the nozzles; a cylindrical first storage member 1 storing the piezoelectric bodies 9; and a grounding member 10 coming in contact with the inside of the first storage member 1.SELECTED DRAWING: Figure 5 【課題】液体吐出ヘッドの接地状態を良好に維持する。【解決手段】液体吐出ヘッド２０２は、液体を吐出するノズルが形成されたノズル形成部材と、ノズルを開閉する開閉部材と、駆動電圧により軸方向に伸縮してノズルを開閉するように開閉部材を作動させる圧電体９と、圧電体９を収容する筒状の第一の収容部材１と、第一の収容部材１の内側に接触する接地部材１０と、を備える。【選択図】図５
