The liquid droplet ejection head has a plurality of nozzles arranged in a fixed arrangement pattern two-dimensionally in a first direction and a direction oblique to the first direction. The nozzles compose a projected nozzle row in the first direction when supposing that the nozzles are projected so as to align in the first direction; first one of the nozzles and second one of the nozzles are located in a juncture region; a distance in a second direction perpendicular to the first direction between the first and second nozzles is larger than a distance in the second direction between other two of the nozzles that are located in a region other than the juncture region and sequenced in the projected nozzle row; third at least one of the nozzles lies substantially halfway between the first and second nozzles; and the first, third and second nozzles are sequenced in the projected nozzle row.
