PROBLEM TO BE SOLVED: To provide a laminated film having the practically sufficient reflecting capacity of a visible region, capable of being stably formed, suppressed in deterioration due to ultraviolet rays, especially yellowing, reduced in the thermal deformation and suitably used as the reflecting plate base material for a liquid crystal display or an internal illumination type electric decorative signboard very excellent in flatness. SOLUTION: The laminated film comprises a reflecting layer A with a void volume ratio of 30-80% and a support layer B with a void volume ratio of 0-25% brought into contact with the reflecting layer A and has a reflectivity of 90% or above and a knurling of which the ridge/valley difference thereof is 5-50μm.
