Liquid ejecting head

A liquid ejecting head comprising a plurality of unit heads, wherein

• each of the unit heads includes a channel structure and a plurality of actuators arranged on the channel structure,
• the channel structure has:
• a plurality of nozzles aligned along a first direction;
• a supply channel extending in the first direction and communicating with the nozzles;
• a return channel extending in the first direction, communicating with the nozzles, and arranged side by side with the supply channel in a second direction crossing the first direction;
• a connecting channel connecting one end in the first direction of the supply channel and one end in the first direction of the return channel;
• a supply port communicating with the other end in the first direction of the supply channel;
• and
• a discharge port communicating with the other end in the first direction of the return channel,
• each of the actuators is configured to apply energy to liquid in the channel structure to cause the liquid to be ejected from one of the nozzles, the actuators being arranged along the first direction to correspond to the nozzles, respectively,
• the unit heads are arranged to be shifted from each other in the first direction,
• the unit heads include two unit heads which are adjacent to each other in a third direction being orthogonal to the first direction and the second direction,
• the two unit heads have a same spacing distance in the first direction between the nozzles, and
• in the two unit heads, a set of the supply port and the discharge port of one unit head and a set of the supply port and the discharge port of the other unit head are arranged to be opposite to each other in the first direction.
