Abstract:
1. A liquid ejecting head comprising: a substrate to which elements for generating energy for ejecting liquid and a supply port for supplying the liquid to be ejected are provided; a plurality of ejection outlets, for ejecting the liquid, provided corresponding to and opposed to the elements; pressure chambers each communicating with an associated ejection outlet; said pressure chambers including a first associated pressure chamber and a second associated pressure chamber, wherein the first associated pressure chamber and the second associated pressure chamber are adjacent to each other with respect to an arrangement direction of said plurality of ejection outlets; and flow paths communicating between said pressure chambers and the supply port, wherein said flow paths include two first flow path portions connected to the first associated pressure chamber, the two first flow path portions being provided along the arrangement direction of said plurality of ejection outlets and communicating with each other in a straight direction through the first associated pressure chamber, wherein said flow paths further include two second flow path portions connected to the second associated the pressure chamber, the two second flow path portions being provided along the arrangement direction of said plurality of ejection outlets and communicating with each other in a straight direction through the second associated pressure chamber, and wherein one of the first flow path portions that is provided on a side of the second associated pressure chamber and one of the second flow path portions that is provided on a side of the first associated pressure chamber at least partly overlap each other with respect to a direction from said plurality of ejection outlets toward said substrate.
