PROBLEM TO BE SOLVED: To provide a method for removal of foreign matter in the nozzle of a liquid discharge device, capable of quickly and surely removing foreign matters adhered inside the nozzle of the liquid discharge device or on the outside thereof, without the risk of the removed foreign matter re-adhering inside the nozzle or at the outside thereof, and capable of effectively removing the foreign matters inside the nozzle that is generated during the process of manufacturing the liquid discharge device. SOLUTION: The method is for removal of the foreign matters in a discharge nozzle 1021 of a liquid droplet discharge device, and in the method, an atmospheric pressure plasma 1033 has a deposit 1031, consisting of a gelatinous material and solidified matter formed by gelatinization and solidification of color filter ink deposited inside a discharge port 1027 of the discharge nozzle 1021 irradiated, and a deposit 1032 deposited on a plate surface 1021a of the discharge port 1027 in the vicinity of the discharge nozzle 1021, thereby removing the deposits 1031 and 1032 from the discharge nozzle 1021.
