Abstract
A liquid discharge head includes multiple nozzles, multiple pressure chambers, a common supply channel, and multiple beams. The multiple nozzles discharge liquid. The multiple pressure chambers communicate with the multiple respective nozzles. The common supply channel communicates with the multiple pressure chambers. The common supply channel is shorter in a short-side direction than in a longitudinal direction perpendicular to the short-side direction. The multiple beams are arranged in a truss shape to connect side walls on lateral sides of the common supply channel in the short-side direction of the common supply channel.
