To provide a liquid discharge head, which can efficiently discharge liquid.SOLUTION: The liquid discharge head comprises: a plurality of liquid chambers provided with nozzles; vibration plates constituting one surfaces of the liquid chambers; piezoelectric elements arranged at positions opposing to the liquid chambers through the vibration plates; and structures, arranged between the vibration plates and the piezoelectric elements, which are larger than plane projected areas of the piezoelectric elements and transmit vibrations caused by the piezoelectric elements to the vibration plates to deform the liquid chambers.SELECTED DRAWING: Figure 1 【課題】液体吐出ヘッドにおいて、液体の吐出を効率よく行う。【解決手段】ノズルが設けられた複数の液室と、前記液室の一面を構成する振動板と、前記振動板を介して前記液室と対向する位置に配置された圧電素子と、前記振動板と前記圧電素子との間に配置され、前記圧電素子の平面投影面積よりも大きく、前記圧電素子による振動を前記振動板に伝達して、前記液室を変形させる構造体と、を備えることを特徴とする。【選択図】図１
