[Problem] The present invention provides a multilayer film having superior heat-ray shielding performance as compared to conventional polymer multilayer films, with the changes in the color tone caused by slight differences in the light incident angle and the film thickness being suppressed. [Means for Solution] The multilayer film of the present invention comprising a constitution in which 50 or more layers of each of two or more thermoplastic resins having different optical properties are alternately laminated with each other, wherein the average reflectance in a wavelength range of 900 to 1,200 nm is 70% or higher; both of the differences between the a* values (”a*) and between the b* values (”b*), respectively, of transmitted light incoming at an angle of 12° and of transmitted light incoming at an angle of 45° are 10 or less; and the multilayer film comprises a bandwidth of not less than 50 nm where the transmittance is 80% or lower in a wavelength range of 400 to 800 nm. |
