Abstract:
There is provide a liquid discharge head including: a supply manifold; a feedback manifold; and a plurality of individual flow channels having: a supply portion, a descender portion, and a feedback portion. The supply manifold has a plurality of supply ports, and the feedback manifold has a plurality of feedback ports. At least part of the supply manifold overlaps with the feedback manifold in the second direction. The plurality of pressure chambers have first pressure chambers forming a first pressure chamber array and second pressure chambers forming a second pressure chamber array. The first pressure chamber array is arranged at one side, of the supply manifold, in a third direction and the second pressure chamber array is arranged at the other side, of the supply manifold, in the third direction. The first pressure chamber array and the second pressure chamber array are connected to the supply manifold.
