PURPOSE: To provide a manufacturing method of the flux cored wire for the welding where the breakage of the wire which becomes a problem in manufacturing the wire especially at high speed drawing, the productivity is improved, and the excellent welding performance is obtained when the flux cored wire for the welding is manufacture. CONSTITUTION: In a manufacturing method of the flux cored wire for the welding where the wire is drawn after the flux is filled in a steel outer shell, the granulated flux is filled where the ultra-fine powder particles of <=0.20μm in grain size are stuck the surface at a ratio of <=1.0% to the total weight of the flux to be filled.
