<p>PROBLEM TO BE SOLVED: To solve the problem in which adjacency crosstalk is not suppressed sufficiently and discharge efficiency is insufficient.SOLUTION: A liquid discharge head has a plurality of nozzles 4 which discharge droplets, a plurality of individual liquid chambers 6 that the nozzles 4 communicate with, a plurality of fluid resistance parts 7 which communicate with the plurality of individual liquid chambers 6, and a liquid introduction part 8 on the upstream side of the fluid resistance parts 7. A width L1 of an inter-fluid-resistance-part partition wall 71 in a nozzle array direction is wider than a width L2 of an inter-individual-liquid-chamber partition wall 61 in the nozzle array direction, the fluid resistance parts 7 each have a plurality of branch flow passages 7a, 7a branched by an island part 70 arranged in a flow passage, and a downstream-side end 70a, sharpened in the flow direction of liquid, of the island part 70 is located upstream from the inter-fluid-resistance-part partition wall 71 in the flow direction of the liquid.</p> |
