PROBLEM TO BE SOLVED: To provide a white laminated film having practically sufficient reflection performance in a visible light region and is stably film-formed, in which degradation (yellowing) by ultraviolet rays is suppressed and deformation by heat is small, and suitably used as a reflection plate base material for a liquid crystal display or an inner irradiation type illumination signboard. SOLUTION: The laminated film comprises a layer A which consists of polyester containing 31 to 60 weight% of inactive particles of 0.3 to 3.0μm average grain size and a layer B which comes into contact with the layer A and consists of polyester containing 1 to 30 weight% of inactive particles of 0.3 to 3.0μm average grain size and the laminated film is used for use where light is reflected with the layer A as an outermost layer.
