An inkjet print head can prevent the deformation of the nozzle layer since a filler supports the nozzle layer and can prevent the degradation of the print quality caused by the inflow of foreign materials into the interval of the fillers. An inkjet print head includes a substrate(10) in which an ink feed hole(15) is formed, an ink chamber(21) which is laminated on the substrate and filled with ink, a chamber layer(20) in which a restrictor(23) connecting the ink feed hole and the ink chamber are formed, a nozzle layer(30) which is laminated on the chamber layer with a nozzle(31), a plurality of fillers arranged at certain intervals on the bottom side of the nozzle layer in order to support the nozzle layer laminated on the substrate in which the ink feed hole is formed, and a foreign material inflow prevention unit formed in each filler in order to prevent the foreign material contained in the ink from inflowing into the interval of the fillers.
