Abstract
It is an object of the present invention to provide an inkjet head and its manufacturing method, which may realize a high resolution while maintaining at a desired strength those walls which define a plurality of ink supply channels between the common ink chamber and each pressure chamber, and securing the adhesion areas on these walls. The inkjet head is miniaturized in a direction in which the pressure chambers are arranged, by arranging a plurality of ink supply channels that are connected to each pressure chamber perpendicular to the direction in which the pressure chambers are arranged.
