A conductive film of the present invention includes an elastomer and a flake-like carbon material. An amount of the flake-like carbon material in the conductive film is 20 parts by mass or more and 60 parts by mass or less when a total solid content excluding a conductive agent is 100 parts by mass. A gloss level of a surface of the conductive film measured at an incidence angle of 20° is more than 0.4% and less than 10%. A method for producing a conductive film of the present invention includes the steps of preparing a liquid composition including an elastomer, a conductive agent including at least one of graphite powder and expanded graphite powder, and a solvent; subjecting the liquid composition to a grinding treatment using a wet jet mill; and applying the liquid composition after the grinding treatment to a base material, and curing the coating film.
