Abstract
An inkjet head includes a flow-path unit and a piezoelectric element. 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 and a nozzle. The piezoelectric element is bonded onto one of the plates by an adhesive. The first plate defines, on one surface onto which the piezoelectric element is bonded, a first groove that extends in a first direction and a plurality of recess portions on one side of the first groove in a second direction, which intersects with the first direction. The recess portions are spaced from each other.
