<p>PROBLEM TO BE SOLVED: To provide a liquid ejection head which can highly accurately regulate nozzle positions among nozzle rows in a liquid ejection head obliquely disposed with the nozzle rows and which makes an assembly step simplified.SOLUTION: A liquid ejection head is provided with a head main body having nozzle rows being disposed side-by-side with nozzles at predetermined nozzle pitches in a first direction and having L rows (L is an integer of 2 or greater) parallel to one another. Each nozzle row was arranged as follows: when nozzle positions of each of the nozzle rows are projected in a third direction perpendicular to a second direction with respect to a virtual line in the second direction intersecting with the first direction by a predetermined angle within a range from 0 to 90 degrees, each of the distances among the nozzles of each of the nozzle rows is represented by M; and when the nozzle positions of the nozzle rows having the L rows are projected in the third direction with respect to the virtual line in the second direction, the nozzle positions overlap with one another among the nozzle rows having the L rows, or distances among the nozzles of the nozzle rows having the L rows are deviated from one another by M×(1/L) in the second direction.</p> |
