[Problem] To provide a laminated reflective film having excellent discoloration resistance and adhesiveness between refractive index layers. [Solution] Disclosed is a laminated reflective film comprising a base material, and a reflective layer that includes a high refractive index layer and a low refractive index layer arranged on the base material, wherein: the high refractive index layer and/or the low refractive index layer include(s) a polyvinyl alcohol-based resin, metal oxide particles, and first metal ions consisting of alkali metal ions and/or alkali-earth metal ions; and the content by percentage of said first metal ions represented by formula (1) is 1.25 or less. |
