According to the present invention, there is provided a film, a method for manufacturing the film, an optical device and a foldable device comprising the film, the film comprising a polymer having a weight average molecular weight of Mf 1 or more represented by the following formula (1), and the polymer The glass transition temperature of the material is 60° C. or higher, and the content of fine particles having a particle size of 10 nm or more and 10 μm or less in the film is 40 parts by mass or less with respect to 100 parts by mass of the polymer. Mf 1 = 6.60×10 (4 + Me/11400) (1) In the formula (1), Me represents the molecular weight between entanglement points of the above polymer. |
