PROBLEM TO BE SOLVED: To provide a transparent laminated film used for relief transparent hologram or the like, having high reflectance, excellent transmission, optimal refractive index, and brightness, in particular, good balance of the brightness and refractive index, and further, improved visual conditions. SOLUTION: The transparent laminated film 10 has a transparent titanium oxide layer 12 formed on at least one face of a transparent base material 11, has a thickness of the transparent titanium oxide layer 12 of 80-120 nm, an average particle size of 10-17 nm, and the brightness of 42-56 cd/m<SP>2</SP>.
