Abstract:
A liquid ejecting head includes: a nozzle array including nozzles via which liquid is to be discharged and which are arrayed in a first direction; a nozzle passage that leads to a nozzle and extends in a second direction intersecting the first direction; a first pressure chamber; a second pressure chamber disposed adjacent to the first pressure chamber in the first direction; a first communicating passage via which the first pressure chamber communicates with an interior of the nozzle passage and which extends in a third direction orthogonal to the first and second directions; and a second communicating passage via which the second pressure chamber communicates with the interior of the nozzle passage and which extends in the third direction. As viewed from the second direction, an inner wall surface of the first communicating passage positioned on a side of the second communicating passage includes a first inclined surface that extends in a fourth direction intersecting the first and third directions.
