The utility model relates to an ink-jet print head, which comprises a plurality of nozzles for jetting ink, a first flat plate layer, a second flat plate layer, an ink-feeding passage, a film-shaped flat plate component, a flow limiting passage and a buffering chamber, wherein, the first flat plate layer is formed by at least one flat plate of a plurality of pressure chambers which are formed in parallel and communicated respectively with the corresponding nozzles; the second flat plate layer is formed by at least one flat plate of a long and shared ink chamber which is formed in the parallel direction of the pressure chambers; the ink-feeding passage is connected with the shared ink chamber and an ink-feeding source; the film-shaped flat plate component is positioned between the first flat plate layer and the second flat plate layer. One end of the flow limiting passage is communicated with the pressure chambers, and the other end of the flow limiting passage is communicated with the shared ink chamber. Besides, the flow limiting passage adjusting the ink flow capacity between the pressure chambers and the shared ink chamber is formed on the flat plate component. The buffering chamber is formed on the contrary side face of the shared ink chamber corresponding to the flat plate layer of the flat plate component.
