ABSTRACT OF THE DISCLOSURE Disclosed is a polyester film having a surface layer whose major component is polyester A. Protrusions are formed on the film surface originating from the crystallization of polyester A. The number of protrusions formed on the surface of the film is not less than 5 x 103/mm2, and the ratio N R of the number of protrusions to the number of particles contained in a surface layer forming the surface of the film is not less than 5. Since most of or the whole of the protrusions are formed by utilizing the crystallization of polyester A without relying particles, generation of voids can be prevented and fine and uniform protrusions having excellent chipping resistance and scratch resistance can be formed.
