PROBLEM TO BE SOLVED: To provide an electrospinning device capable of forming an electric field between a nozzle and an electrode by increasing an electrification amount of the nozzle while keeping a state of lower viscosity of molten resin.SOLUTION: An electrospinning device 10 comprises: a molten resin discharging device 20; a conductive body nozzle 31; an electrode 32 for generating an electric field between the electrode and the nozzle 31; a power supply device 62 that applies voltage on the nozzle 31 or the electrode 32; and a collection part 60 that collects fibrous resin. The electrode 32 is a concave-surfaced electrode on which a concave surface is disposed so as to surround the nozzle 31. An electric insulating part 40, on which a flow passage 43 for passing the molten resin is formed, is disposed between the molten resin discharging device 20 and the nozzle 31. The molten resin discharging device 20 is separated from the nozzle 31 and the electrode 32 by the electric insulating part 40. A gas flow passage 44 is formed in the electric insulating part 40 so as to surround the resin flow passage 43.SELECTED DRAWING: Figure 1 |
