Ink head
An ink head includes: a common ink chamber; a first nozzle including a first nozzle hole, a first flow channel and the common ink chamber, and a first actuator; and a second nozzle including a second nozzle hole, a second flow channel and the common ink chamber, and a second actuator, the second nozzle being adjacent to the first nozzle in a first direction. The first flow channel is linked to the common ink chamber via a first opening. The second flow channel is linked to the common ink chamber via a second opening. A center position of the first opening is shifted from a center position of the second opening in at least a third direction, the third direction crossing the first direction when viewed along a second direction, the second direction being from the common ink chamber toward the first flow channel.
