Laminated Film

Abstract: The present invention addresses the problem of providing a laminated film that exhibits no interlayer peeling even with continued use over a long period, and that exhibits excellent reflective properties with respect to visible light. The present invention is a laminated film characterized by: having three or more ordered arrays that are continuous and that comprise thermoplastic resin layers of three differing types; and simultaneously satisfying a condition X and a condition Y. Condition X: When the thermoplastic resin layers of three differing types are defined as layer A, layer B, and layer C, the thickness ratio A/B of the layer A to the layer B in the ordered arrays is 0.60-5.00, and the thickness ratio C/B of the layer C to the layer B in the ordered arrays is 0.70-5.00. Condition Y: Maximum reflectance at a wavelength of 400-800 nm is 35-100%.
