A filament type nano-sized long fiber and a method of producing the same. In the method, a spinning solution or a spinning melt is electro-spun in drops using a spinneret to which a critical voltage is applied, and the spun drops are continuously collected on a multi-collector. The spinning solution is produced by dissolving a blend or copolymer consisting of two or more kinds of polymers in a solvent. The spinning melt is produced by melting the polymers. The multi-collector is selected from the group consisting of a plate type collector, a roll type collector, and a combination thereof. The filament type nano-sized long fiber is processed into a yarn through one step during the electrospinning process, and thus, mechanical properties are better than those of a conventional nanofiber non-woven fabric. Consequently, the filament type nano-sized long fiber can be utilized for the extended application.
