PROBLEM TO BE SOLVED: To provide a method for producing a continuous filament nonwoven fabric that can be stably and efficiently fibrillated and drawn and shows high homogeneity and good in filament group opening and dispersion. SOLUTION: When the groups of a plurality of continuous filaments are melt-extruded from spinning nozzles, fibrillated and then drawn by the friction pulling force to give the objective nonwoven fabric, the continuous filaments are pulled with a high-speed fluid to which a vibration of 0.1-60 Hz is applied to produce the objective continuous filament nonwoven fabric with a filament fineness of 0.1-22 dtex.
