Abstract
A liquid discharge head includes i) a recording-element substrate configured to discharge a liquid, ii) a cuboid-like liquid tank configured to support the recording-element substrate and to store the liquid to be discharged from the recording-element substrate, and iii) an absorbent accommodated in a compressed state in the liquid tank and configured to absorb and hold the liquid. In the liquid discharge head, multiple projections are formed on a bottom of the liquid tank. In addition, as viewed in plan in a direction orthogonal to the bottom, the projections are disposed so as to surround or straddle an injection position at which the liquid is injected into the absorbent using an injection needle.
