LIQUID DISCHARGE HEAD, LIQUID DISCHARGE UNIT, AND LIQUID DISCHARGE DEVICE

To inhibit fluctuation of discharge characteristics with a simple structure.SOLUTION: A liquid discharge head includes: nozzles 4 which discharge a liquid; pressure chambers 6 respectively leading to the nozzles 4; individual supply passages 7 respectively leading to the pressure chambers 6; and a common supply passage 10 leading to the individual supply passages 7. The individual supply passages 7 include: a first passage part 7A and a second passage part 7B in which fluid resistance is higher than in the pressure chambers 6; and a third passage part 7C which is disposed between the first passage part 7A and the second passage part 7B and in which the fluid resistance is lower than in the first passage part 7A and the second passage part 7B.SELECTED DRAWING: Figure 3 【課題】簡単な構成で吐出特性の変動を抑制する。【解決手段】液体を吐出する複数のノズル４と、複数のノズル４にそれぞれ通じる複数の圧力室６と、複数の圧力室６にそれぞれ通じる複数の個別供給流路７と、複数の個別供給流路７に通じる共通供給流路１０とを備え、個別供給流路７は、圧力室６よりも流体抵抗が高い第１流路部７Ａ及び第２流路部７Ｂと、第１流路部７Ａと第２流路部７Ｂとの間に配置され、第１流路７Ａ及び第２流路部７Ｂよりも流体抵抗が低い第３流路部７Ｃとを含む。【選択図】図３
