PROBLEM TO BE SOLVED: To suppress an ink leak by preventing cracks from occurring in the circumference of an opening part of an ink feeding chamber at the time of cutting an inkjet head. SOLUTION: The inkjet head is provided with a piezoelectric base 30, a covering base 20, a nozzle plate and a manifold. The piezoelectric base 30 has a plurality of ink chambers 31. The covering base 20 has the ink feeding chamber 21 provided with the opening part 21A on both side end faces 83 and 84. The nozzle plate is connected to the front end face 81, and the manifold is connected to the side end face. The inkjet head has recesses 23 and 24 at least on one side of the piezoelectric base 30 and the covering base 20. The recesses 23 and 24 cause the piezoelectric base 30 and the covering base 20 to separate in the entire region at least on one side of the forward part on the front end face 81 side from the front end fringe of the opening part 21A or the rear part of the back end face side from the back end fringe, within a region having a predetermined dimension from the side end faces 83 and 84.
