PROBLEM TO BE SOLVED: To provide an electrospinning apparatus capable of enhancing productivity of nanofibers and achieving space saving, and a nanofiber production apparatus using the electrospinning apparatus.SOLUTION: An electrospinning apparatus 1 includes: an electrode 10 having a cylindrical recessed concave surface 11; and a needle-like nozzle 20 for discharging raw material liquid disposed to be surrounded by the cylindrical recessed concave surface 11 of the electrode 10. A surface facing the nozzle 20 of the electrode 10 is coated with a dielectric 30, and nanofibers are formed from raw material liquid discharged from a tip 20a of the nozzle 20 in a state that an electric field is generated between the electrode 10 and the nozzle 20. The nozzle 20 is disposed so that a direction in which the nozzle 20 extends passes the center of a circle formed by one opening end in the cylindrical recessed concave surface 11 of the electrode 10 or in the vicinity of the center and the tip 20a of the nozzle 20 is located in a plane including the circle formed by the opening end or located inside the recessed concave surface 11 rather than the plane. |
