Zusammenfassung:	To provide a liquid discharge head which enables a nozzle cover to be joined without removing a water repellent film of a nozzle surface and achieves high joint strength compared to a case in which the nozzle cover is directly joined to the nozzle surface.SOLUTION: A liquid discharge head includes: a nozzle plate 2 in which a water repellent film is formed on a nozzle surface having nozzles 20; a nozzle cover 101 which protects at least a part of the nozzle surface; and an intermediate member 102 which is disposed between the water repellent film and the nozzle cover in a liquid discharge direction and joined to the water repellent film and the nozzle cover.SELECTED DRAWING: Figure 2 【課題】ノズル面の撥水膜を除去することなくノズルカバーを接合することができ、ノズル面に直接ノズルカバーを接合する場合に比べて接合強度が高い液体吐出ヘッドを提供する。【解決手段】ノズル２０を有するノズル面に撥水膜が形成されたノズル板２と、前記ノズル面の少なくとも一部を保護するノズルカバー１０１と、液体吐出方向において前記撥水膜と前記ノズルカバーとの間に配置され、前記撥水膜と前記ノズルカバーのそれぞれに対して接合する中間部材１０２と、を有することを特徴とする。【選択図】図２
