A liquid discharge head comprising: a nozzle plate having multiple nozzles arrayed at a predetermined pitch d corresponding to a recording resolution in a longitudinal direction of the nozzle plate, wherein the multiple nozzles 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 as multiple sub-nozzles, where P is an integer of one or more, the multiple sub-nozzles are arrayed in the longitudinal direction at a first interval of d × P, each of the P number of sub-nozzle groups (SBN1, SBN2) includes sub-nozzle rows (11sb1, 11sb2) each including the multiple sub-nozzles 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, and a set of the sub-nozzle rows (11sb1, 11sb2) of the P number of the sub-nozzle groups (SBN1, SBN2) arrayed in one row in the first inclination direction form a nozzle row, the nozzle row has N number of the multiple sub-nozzles in a central region of the nozzle plate in the longitudinal direction, the nozzle row has M number of the multiple sub-nozzles less than the N number of the multiple sub-nozzles, the M number of the multiple sub-nozzles arrayed at a first end portion of the nozzle plate in the longitudinal direction, and the nozzle row having N - M number of the multiple sub-nozzles at a second end portion opposite to the first end portion of the nozzle plate across the central region in the longitudinal direction, characterised in that a short side of the nozzle plate is in a second inclination direction (θa) inclined relative to the longitudinal direction and the transverse direction, and the first inclination direction is different from the second inclination direction. a nozzle plate having multiple nozzles arrayed at a predetermined pitch d corresponding to a recording resolution in a longitudinal direction of the nozzle plate, wherein the multiple nozzles 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 as multiple sub-nozzles, where P is an integer of one or more, the multiple sub-nozzles are arrayed in the longitudinal direction at a first interval of d × P, each of the P number of sub-nozzle groups (SBN1, SBN2) includes sub-nozzle rows (11sb1, 11sb2) each including the multiple sub-nozzles 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, and a set of the sub-nozzle rows (11sb1, 11sb2) of the P number of the sub-nozzle groups (SBN1, SBN2) arrayed in one row in the first inclination direction form a nozzle row, the nozzle row has N number of the multiple sub-nozzles in a central region of the nozzle plate in the longitudinal direction, the nozzle row has M number of the multiple sub-nozzles less than the N number of the multiple sub-nozzles, the M number of the multiple sub-nozzles arrayed at a first end portion of the nozzle plate in the longitudinal direction, and the nozzle row having N - M number of the multiple sub-nozzles at a second end portion opposite to the first end portion of the nozzle plate across the central region in the longitudinal direction, characterised in that a short side of the nozzle plate is in a second inclination direction (θa) inclined relative to the longitudinal direction and the transverse direction, and the first inclination direction is different from the second inclination direction.
