PROBLEM TO BE SOLVED: To improve in sightability on an reflected image at a scotopic vision, besides being large in a nonglaring effect against the light of a headlamp. SOLUTION: High refractive reflecting layers 21, 23 and 25 and low refractive reflecting layers 22, 24 and 26 are alternately laminated into six layers, and mirror reflectance (40 to 50%) of blue light (wavelength 440 to 460nm) is constituted so as to satisfy the standard of a car mirror. In consequence, with the interference action of multilayered reflective films 2 utilized, the mirror reflectance (40 to 50%) of the blue light (wavelength 440 to 460nm) is able to satisfy the standard of the car mirror. Moreover, since it assumes a blue color, a nonglaring effect against the light of a headlamp grows larger and, sightability for a reflected image at a scotopic vision becomes improved. |
