Abstract
A liquid discharge head includes nozzles, pressure chambers, individual supply channels, individual collection channels common supply channel branches, and common collection channel branches. The common supply channel branches communicate with two or more of the individual supply channels. The common collection channel branches communicate with two or more of the individual collection channels. The nozzles are two-dimensionally arranged in a matrix and arranged in at least a first direction and a second direction intersecting with the first direction at an inclination. The common supply channel branches and the common collection channel branches extend in the first direction. The common supply channel branches and the common collection channel branches are alternately arranged in the second direction. An arrangement interval between the common supply channel branches and the common collection channel branches is equal to or more than twice an arrangement interval between the nozzles arranged in the second direction.
