PROBLEM TO BE SOLVED: To provide an inkjet head wherein foreign matter created in a process of manufacturing the inkjet head is surely removed in a condition that a filter in the inkjet head and an ink supply means from the ink cartridge are attached thereto. SOLUTION: This inkjet head is constituted of a fluid channel plate 1 having a common liquid chamber 1c with a filter 7 and a plurality of pressurizing liquid chambers 1e, a nozzle plate 2 having nozzles 2a respectively corresponding to the pressurizing liquid chambers 1e to be bonded to the fluid channel plate 1, and drive elements formed corresponding to the pressurizing liquid chambers 1e. The fluid channel plate 1 is equipped with liquid discharge holes 8, 8 each having the sufficiently small fluid resistance. A cleaning liquid is allowed to flow from the side of the pressurizing liquid chamber 1e and the upstream side of the filter 7 before the nozzle plate 2 is bonded to the fluid channel plate 1, and then foreign matter 10 entering the inkjet head in the process of manufacturing is surely removed.
