PURPOSE: A release film is provided to improve workability for winding process, post-processing, and carrying by controlling a frictional coefficient. CONSTITUTION: A polyester group substrate film layer is prepared. A coating layer uses composition including silicon binder resin whose average particle diameter is 20nm~10um in single-side or both sides of the substrate film layer. The substrate film layer is the one-axis or biaxial-stretched polyethyleneterephthalate film. The frictional coefficient of the release film is 0.10~0.25. The shape of the silica particle is globular shape.
