Abstract:
A liquid ejecting head including a plurality of nozzles, a row of individual flow paths that includes a plurality of individual flow paths arranged in parallel along a second axis orthogonal to the first axis when viewed in a direction of the first axis, and a common liquid chamber that is commonly in communication with the plurality of individual flow paths. In the liquid ejecting head, the plurality of individual flow paths include a first individual flow path and a second individual flow path that are adjacent to each other in the row of individual flow paths, and the level of a first opening that is a connection port between the common liquid chamber and the first individual flow path and the level of a second opening that is a connection port between the common liquid chamber and the second individual flow path are different.
