The present invention relates to an electrospinning device for manufacturing nanofibers. The purpose of the present invention is to provide an electrospinning device for manufacturing nanofibers including a case, wherein a lower part thereof is formed of a conductive material and an upper part thereof is formed of an insulating material, thereby enabling the omission of an insulating member at the upper part in the case for attaching a collector, thus simplifying the whole structure of the electrospinning device for manufacturing nanofibers, and reducing costs for facilities and the total costs. The present invention comprises: a case having a conductive property; a collector attached to the case by an insulating member; a nozzle block placed to face the collector and having a plurality of nozzles for discharging a polymer spinning solution; and a power device for applying power between the nozzle block and the collector, wherein one electrode among the cathode and the anode of the power device is connected to the collector and the other electrode is connected to the nozzle block and the case. The case has a lower part formed of a conductive material and an upper part formed of an insulating material, has the collector directly contacting with the inner surface of the upper part of the case, and satisfies that a>=6mm and a+b>=50mm, wherein ″a″ represents the thickness of the case formed of an insulating material, and ″b″ represents a distance between the inner surface of the case formed of an insulating material and the outer surface of the collector. |
