1. An electrospinning apparatus for producing ultrafine fibers, comprising:
a high voltage supplier to apply high voltage to a spinning nozzle to charge a solution containing a dissolved polymer material;
the spinning nozzle including at least one hollow needle to receive the charged solution and jet the charged solution in the form of filaments;
a cylindrical metal guide positioned around the hollow needle at a lower end of the spinning nozzle, wherein high voltage is applied to the cylindrical metal guide to control droplet stability of the charged solution; collector positioned under the spinning nozzle to collect charged filaments; and
a strip-shaped metal guide including a plurality of strip-shaped metal plates radially arranged around the cylindrical metal guide and extending in a direction perpendicular to a nozzle arrangement direction.
