Claim:
1. A method of manufacturing an antistatic film, comprising: a preparation step of preparing a mixed liquid by mixing a polyvinyl alcohol with an aqueous conductive polymer dispersion in which a conductive composite containing a n-conjugated conductive polymer and a polyanion is included in a water-based dispersion medium, wherein the content ratio of the polyvinyl alcohol in the mixed liquid is 0.01% by mass to 10% by mass; a coating step of obtaining a coating film by coating at least one surface of a film base with the mixed liquid, wherein an amorphous polyethylene terephthalate film is used as the film base; and a drying and stretching step of forming an antistatic layer by drying and stretching both the coating film and the film base with heating, wherein the dried coating film is heated to 200° C. or higher after the drying and stretching step, and then cooled to a crystallization temperature of the polyethylene terephthalate.
