Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink jet device that can accurately detecting a nonejection nozzle or a defective nozzle without landing precision or the like when applying ink on a large area substrate.SOLUTION: In the ink jet device, a substrate 3 which is a printing medium and a plate 6 for discharge inspection are arranged on the same height so that correlation is taken between application results on the substrate 3 and on the plate 6 for discharge inspection. Accordingly, a coating state on the substrate 3 is improved by correcting displacement of application droplet or a nonejection state of a nozzle on the basis of inspected patterns of the application result on the plate 6 for discharge inspection.
