PROBLEM TO BE SOLVED: To facilitate recycling of a printed board with an IC for driving loaded thereon in the case of a failure at only an inkjet head, and to facilitate reuse of the inkjet head in the case of a failure at only the printed board with the IC for driving loaded thereon. SOLUTION: The inkjet head 1 has a cavity plate 17 where a plurality of ink pressure chambers 17a are arranged adjoining to each other, a piezoelectric element unit 18 disposed at the cavity plate 17, and a plurality of driving electrodes 18b formed on the piezoelectric element unit 18 to be opposite to the ink pressure chambers 17a of the cavity plate 17. A flexible printed board 19 is connected for sending drive signals to the driving electrodes 18b. An adhesive layer 19f with a permanent magnet powder mixed is attracted by its magnetic force and connected to an adhesive layer 18c with an iron powder mixed which is formed on the driving electrodes 18b, whereby between the driving electrodes 18b and electrode lands 19e of the flexible printed board 19 is made conductive.
