Abstract: Embodiments disclose an optical material having a visual confirmation effect due to higher directivity of light reflection than a conventional optical material. Embodiments can include a laminate having a multilayer laminated film in which 11 or more layers of different thermoplastic resins are alternately laminated. With respect to light in a wavelength range of 400 to 700 nm and that is perpendicularly incident on an outer surface of the multilayer laminated film, the laminate has an average transmittance in the above wavelength range of 50% or more. When average reflectances in a wavelength range of 400 to 700 nm with respect to S-wave light in the wavelength range, incident at angles of 20° and 70° with respect to the normal line of the outer surface of the film at azimuths ϕn (n: 1 to 5), are given as Rs20(ϕn) and Rs70(ϕn), respectively, the laminate satisfies, at least one azimuth ϕn:Rs70(ϕn)−Rs20(ϕn)≥50(%).
