PROBLEM TO BE SOLVED: To provide an inkjet head of which the discharging precision is high, and of which the wiping property is favorable. SOLUTION: This inkjet head 1 is equipped with a common ink chamber 10 which houses ink, and a pressure chamber 6 which communicates with the common ink chamber 10 between a pair of boards 2 and 3. A nozzle 21 communicating with the pressure chamber 6 is formed on the surface of one board 2 of a pair of the boards, and the ink housed in the pressure chamber is discharged through the nozzle 21 by pressure fluctuation of the pressure chamber 6. At a section corresponding to the common ink chamber 10 of the board 2, a recess section 22 which is formed by processing the surface on the opposite side from the discharging side of the board 2 is provided. By reducing the thickness of the board 2 by the recess section 22, a flexible buffer wall 10a for buffering the pressure fluctuation in the common ink chamber is formed on the board 2. In the meantime, a continuous surface from the buffer wall 10a to the opening section of the nozzle 21, which is a surface on the discharging side of the board 2, is formed into a flat surface.
