An inkjet head includes a flow-path unit. The flow-path unit includes a plurality of plates that are stacked and define a common ink chamber and a plurality of ink flow paths communicating with the common ink chamber. The plurality of plates include a first plate and a second plate that are bonded to each other by an adhesive. The first plate defines a plurality of ink supply holes that make up a part of the ink flow paths. The first plate defines a first groove in a second region other than a first region where the first plate and the second plate contact with each other. The first groove extends in a direction, which intersects with a longitudinal direction of the inkjet head.
