Liquid discharge head

A liquid discharge head comprising:

• a plurality of pressure chambers forming a first pressure chamber group and a second pressure chamber group, the first pressure chamber group including a part of the pressure chambers aligned in a first direction orthogonal to a vertical direction, and the second pressure chamber group including another part of the pressure chambers aligned in the first direction, the second pressure chamber group being arranged side by side relative to the first pressure chamber group in a second direction orthogonal to the vertical direction and crossing the first direction;
• a return channel extending in the first direction between, in the second direction, the pressure chambers included in the first pressure chamber group and the pressure chambers included in the second pressure chamber group;
• and
• a plurality of 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 plurality of return connecting channels is not less than a maximum height of an upper surface of one of the plurality of pressure chambers which is connected to the return channel by each of the plurality of return connecting channels.
