PROBLEM TO BE SOLVED: To provide a film by forming the film from a polyester having good crystallinity and a low melting point. SOLUTION: The film is obtained by forming the film from the polyester. Furthermore, the polyester contains terephthalic acid as a dicarboxylic acid component and 1,6-hexanediol and ethylene glycol as a diol component and≥50 mol% of the whole diol component is the 1,6-hexanediol. The film is obtained by forming the film from the polyester having 100-150°C melting point and a DSC curve exhibiting temperature falling crystallization determined from the DSC satisfying formula (1): b/a≥0.02 mW/mg°C.
