PROBLEM TO BE SOLVED: To provide an easily adhesive syndiotactic polystyrene-based stretched film which has good adhesiveness between a film and an adhesiveness-improving layer, has excellent adhesiveness, when laminated to an ink layer or a laminate layer, and has excellent profitability, recyclability and environmental compatibility, when produced. SOLUTION: This easily adhesive syndiotactic polystyrene-based stretched film is characterized by laminating an adhesiveness-improving layer comprising a water-soluble and/or water-dispersible polyurethane-based resin to at least one side of a stretched film comprising a styrenic polymer having a syndiotactic structure. This easily adhesive syndiotactic polystyrene-based stretched film is especially preferably characterized in that the adhesiveness-improving layer is formed by coating an un-stretched film or monoaxially stretched film with a polymer aqueous dispersion, monoaxially or diaxially stretching the coated film once or more, and then thermally treating the stretched film.
