1. A liquid ejecting head, comprising:
a nozzle face having nozzles configured to eject liquid;
a filter through which the liquid passes;
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, the filter constituting a part of a wall surface of the downstream chamber;
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
one end of the first flow passage is connected to the first outlet,
one end of the second flow passage is connected to the second outlet,
the other end of the first flow passage and the other end of the second flow passage are connected to the common flow passage, and
in plan view perpendicular 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.
