Abstract

A liquid discharge head (101) includes: a nozzle plate (10) having multiple nozzles (11) arrayed at a predetermined pitch (d) corresponding to a recording resolution in a longitudinal direction of the nozzle plate (10). The multiple nozzles (11) are divided into P number of sub-nozzle groups (SBN1, SBN2), each of the P number of sub-nozzle groups (SBN1, SBN2) including the multiple nozzles (11) as multiple sub-nozzles (11), where P is an integer of one or more, the multiple sub-nozzles (11) are arrayed in the longitudinal direction at a first interval of (d × P), and each of the P number of sub-nozzle groups (SBN1, SBN2) includes sub-nozzle rows (11sb1, 11sb2) each including the multiple sub-nozzles (11) arrayed at the first interval of (d × P) in the longitudinal direction and in a first inclination direction inclined relative to the longitudinal direction and a transverse direction orthogonal to the longitudinal direction.
