PURPOSE: A wire drawing apparatus is provided to prevent slip of a wire due to an excessive frictional force by reducing surface pressure between the wire and a capstan. CONSTITUTION: A wire drawing apparatus comprises a drawing chamber(110), three or more rotary shafts, capstans(130), and dies(D). The drawing chamber accommodates wet lubricant. The rotary shafts are arranged inside the drawing chamber, corresponding to the vertexes of a polygon. A wire(160) is wound around winding parts of the capstans. The capstans are respectively coupled to the rotary shafts inside the drawing chamber. The dies are installed between the capstans.
