PROBLEM TO BE SOLVED: To solve the problem that refreshing of a filter has been impossible heretofore. SOLUTION: In this inkjet head, a plurality of pressurizing chambers for pressurizing ink, a plurality of nozzles each coupling to the pressurizing chambers, respectively, and a plurality of diaphragms forming cover plates of the pressurizing chambers are formed to be juxtaposed, an ink channel constituted of a manifold for supplying ink to the plurality of pressurizing chambers and an ink supply path coupling the manifold to an ink tank is formed, and the ink is ejected from the nozzles by using a pressurizing means. A filter is formed on the manifold, and two ink supply paths are provided to the manifold. One of the ink supply paths is coupled to the pressurizing chambers through the filter and the other is coupled to the pressurizing chambers without the filter to form a through-hole.
