ink jet head including filtering element formed in a single body with substrate and method of fabricating the same

It provides an ink jet head and a method of manufacturing the same provided with a filter member made of a substrate and integrally. The inkjet head is disposed on the top surface of the substrate includes a plurality of pressure-generating elements to generate pressure for ink ejection. An ink supply port penetrating through the substrate is disposed to be spaced apart from the pressure-generating elements. Between the ink supply port with the pressure-generating element, from the top surface of the substrate and process the predetermined depth Li is the width of the manifold defined by the ink supply port is disposed. But provide filter openings therebetween on the bottom surface of the manifold, with a plurality of filtering pillars consisting of the substrate and integrally arranged. The ink channel and the ink chamber to open to the upper surface of the substrate to the manifold direction ink chambers, wherein the ink chambers each including therein said pressure-generating elements and that includes a nozzle for each fluid communication yi flow path structure defining a flow path is disposed.
