Abstract
An inkjet head has a channel unit including a manifold extending in one predetermined direction and a plurality of individual ink channels extending from the manifold to nozzles through pressure chambers respectively. The channel unit has a plurality of manifold plates for forming the manifold, damper plates provided between two plates of the plurality of manifold plates and communication holes. The damper plates partition the manifold into two spaces and have a damper chamber for absorbing a fluctuation of ink pressure in the manifold. The two spaces partitioned by the damper plates communicate with each other through the communication holes.
