PROBLEM TO BE SOLVED: To provide an inkjet head and its manufacturing method capable of shortening a manufacturing process by integrally forming the membrane of a pressure absorbing space in the case of machining a board for manufacturing the inkjet head, and easily absorbing the pressure change of a manifold to prevent crosstalk with a pressure chamber by providing the pressure absorbing chamberspace in the side wall direction of the manifold, thereby obtaining a higher printing quality. SOLUTION: The method of manufacturing the inkjet head that includes: forming in a first board an inlet, which penetrates the first board and through which ink may flow in, and the pressure chamber, which is formed as a recess in a surface of the first board; forming in a second board the manifold, which is to be connected with the inlet, the pressure absorbing space, which is positioned adjacent to the manifold and partitioned by the membrane, and an ink channel, which penetrates the second board and which is to be connected with the pressure chamber; forming in a third board a nozzle, which is to be connected with the ink channel; and stacking in order and attaching the first board, the second board, and the third board.
