PROBLEM TO BE SOLVED: To provide an easily adhesive syndiotactic polystyrene-based stretched film improved in the adhesion with an adhesiveness modified layer, enhanced in adhesiveness when an ink layer or a laminate layer is laminated and also enhanced in economical efficiency, recyclability and environnmental fitting properties at the time of production. SOLUTION: This easily adhesive syndiotactic polystyrene-based stretched film is constituted by laminating the adhesiveness modified layer comprising a water dispersible ethylene/vinyl ester copolymer resin on at least one side of a stretched film comprising a styrenic polymer having a syndiotactic structure. Especially, the adhesiveness modified layer is preferably formed by coating a non-stretched or uniaxially stretched film with an aqueous polymer dispersion and stretching the coated film uniaxially or biaxially once or above before heat-treating the same.
