PROBLEM TO BE SOLVED: To provide a new reflective film. SOLUTION: The multilayered polymer film 10 including main components of a plurality of alternate layers of crystalline naphthalene dicarboxylic acid polyester 12 and a different selected polymer 14 contains a film having a thickness of the layer smaller than 0.5μm and also a refractive index for at least one in-plane axis of the crystalline naphthalene dicarboxylic acid ester layer higher than that of the adjacent layer of the selected polymer.
