PURPOSE: A manufacturing method of polaroid film and a polaroid film manufactured therefrom are provided to control thickness of the nano fiber with the speed of electricity emission and rotation speed of wind roll, and to form pattern by arranging nano fiber along the electric field in which voltage is sanctioned to the wind roll. CONSTITUTION: The nano fiber(40) is obtained by electricity-emitting the polymer. The nano tube pattern is formed on the base film(50) by sanctioning the electric field, in the roll(20) in which the base film is wound, and winding. The base film in which nano tube is arranged is orientated.
