Patent ID: 7524020

Claim:
A liquid ejecting head comprising a plurality of arrays of liquid ejecting portions each having a nozzle for ejecting a droplet, wherein: the nozzles are alternately arranged along a straight line R 1 and a straight line R 2 that extend parallel to each other but at a distance δ from each other; a distance, with respect to the direction of the straight lines R 1 and R 2 , between two adjacent ones of the nozzles respectively arranged on the straight line R 1 and the straight line R 2 is set to a fixed value P; and the liquid ejecting portions arrayed along at least one of the straight lines R 1 and R 2 are configured so that at least one liquid is ejected at an angle of 90+β degrees from each of the liquid ejecting portions while being deflected to the other straight line side, wherein, β is equal to tan−1 (δ/2H), and H is the distance between a recording medium and a nozzle surface.
