Abstract:
There is provided a liquid discharge head including: a plurality of pressure chambers including pressure chambers aligned in a first direction orthogonal to a vertical direction so as to form a first pressure chamber group, and pressure chambers aligned in the first direction so as to form a second pressure chamber group arranged side to side relative to the first pressure chamber group in a second direction; a return channel extending in the first direction; and return connecting channels each connecting the return channel and one of the plurality of pressure chambers to each other, wherein a height of an upper surface of each of the return connecting channels is not less than a height of an upper surface of one of the plurality of pressure chambers which is connected to the return channel by each of the return connecting channels.
