Abstract
A liquid ejection head comprises a plurality of ejection orifices for ejecting liquid, a liquid supply flow path for supplying liquid to the plurality of ejection orifices and a plurality of branch flow paths branched from the liquid supply flow path each being held in communication with corresponding one of the plurality of ejection orifices. The plurality of ejection orifices form a first row and a second row each extending in parallel with each other. The first and second rows of ejection orifices are partially overlapping with each other as viewed in the direction orthogonal relative to the extending direction. The flow rate in the branch flow paths held in communication with the ejection orifices located in the overlapping part is made greater than the flow rate in the branch flow paths held in communication with the ejection orifices located in the non-overlapping part.
