A polyimide film, which is produced by the reaction of a tetracarboxylic acid component comprising 3,3′,4,4′-biphenyltetracarboxylic dianhydride as the main component and a diamine component comprising p-phenylenediamine as the main component, is heated at a temperature of from 460° C. to 550° C., and then water or an alkaline aqueous solution is sprayed on a surface of the polyimide film for surface treatment, thereby improving adhesiveness, while maintaining the excellent properties inherent in the polyimide film.
