Abstract:
A liquid ejecting head includes: a nozzle face; a filter; a downstream chamber that includes a first outlet and a second outlet for discharging the liquid, the downstream chamber being located downstream of the filter; a first flow passage that is in communication with the downstream chamber through the first outlet; a second flow passage that is in communication with the downstream chamber through the second outlet; and a common flow passage that is in communication with the first flow passage and the second flow passage, wherein, as viewed perpendicularly to the nozzle face, the first outlet is located at a position that is shifted from a center of the downstream chamber in a first direction, and the second outlet is located at a position that is shifted from the center of the downstream chamber in a second direction that is opposite of the first direction.
