To provide a liquid discharge head configured so that liquid can be filled into a common liquid chamber.SOLUTION: A liquid discharge head according to an embodiment comprises a plurality of pressure chambers, a common liquid chamber, a liquid supply port and a liquid ejection port. The plurality of pressure chambers are arranged in a first direction. The common liquid chamber, communicated with the plurality of pressure chambers respectively, has a ceiling plane which rises high from one end side of the arrangement of the pressure chambers toward the other end side when the pressure chambers are arranged in a horizontal direction. The liquid supply port is communicated with the common liquid chamber, at a central part of the arrangement of the pressure chambers. The liquid ejection port is communicated with the common liquid chamber, at an end part at which the ceiling plane rises high.SELECTED DRAWING: Figure 4 【課題】液体を共通液室内に充填することのできる液体吐出ヘッドを提供する。【解決手段】実施形態の液体吐出ヘッドは、複数の圧力室、共通液室、液体供給口、および液体排出口を備える。複数の圧力室は、第１の方向に配列する。共通液室は、複数の前記圧力室の夫々に連通し、前記圧力室の配列方向を水平方向に位置させたときに前記圧力室の配列の一端側から他端側に向かって高くなる天井面を有する。液体供給口は、前記圧力室の配列の中央部で前記共通液室に連通する。液体排出口は、前記天井面が高くなる端部で前記共通液室に連通する。【選択図】図４
