To suppress voltage drop caused by resistance of wiring.SOLUTION: A liquid discharge head for discharging a liquid comprises: an input part to which a signal is input; a nozzle array in which a plurality of nozzles for discharging a liquid are arranged in a prescribed direction, the nozzles including at least, a first nozzle, a second nozzle provided on a position closer to the input part than the first nozzle, and a third nozzle provided between the first nozzle and the second nozzle; a first energy generation element corresponding to the first nozzle; a second energy generation element corresponding to the second nozzle; a third energy generation element corresponding to the third nozzle; and a wiring part for coupling the input part with the first, second and third energy generation elements. A path length on the wiring part between the input part and the third energy generation element is shorter than a path length on the wiring part between the input part and the first energy generation element, and is shorter than a path length on the wiring part between the input part and the second energy generation element.SELECTED DRAWING: Figure 7 【課題】配線の抵抗に起因した電圧降下が抑制される。【解決手段】液体吐出ヘッドは液体を吐出する液体吐出ヘッドであって信号が入力される入力部と第１ノズルと第１ノズルよりも前記入力部に近い位置に位置する第２ノズルと第１ノズルと第２ノズルの間に位置する第３ノズルを少なくとも含む液体を吐出する複数のノズルが所定方向に配列されたノズル列と第１ノズルに対応する第１エネルギー生成素子と第２ノズルに対応する第２エネルギー生成素子と第３ノズルに対応する第３エネルギー生成素子と前記入力部第１エネルギー生成素子第２エネルギー生成素子および第３エネルギー生成素子を接続する配線部と、を有し前記入力部と第３エネルギー生成素子との間の前記配線部における経路長は前記入力部と第１エネルギー生成素子との間の前記配線部における経路長よりも短く、且つ前記入力部と第２エネルギー生成素子との間の前記配線部における経路長よりも短い。【選択図】図７
