Liquid discharge head

A liquid discharge head comprising a first channel member including a liquid channel,

• wherein the liquid channel includes:
• a plurality of pressure chambers connected respectively to a plurality of nozzles and arranged in a first direction;
• a plurality of throttle channels connected to the pressure chambers and extending from connection portions of the pressure chambers to provide fluid flow in a second direction, which is orthogonal to the first direction;
• and
• a plurality of coupling channels arranged in the first direction, each of the coupling channels being connected to two or more of the throttle channels that are adjacent to each other in the first direction, extending in a third direction orthogonal to the first direction and the second direction, having a plurality of openings in a surface in the third direction of the first channel member.
