PROBLEM TO BE SOLVED: To provide a laminated polyester film having an excellent solvent resistance. SOLUTION: The laminated polyester film has a layer X of a resin (P) composed of a polyester resin component (A) and a glycidyl group-containing acrylic compound component (B) on at least one surface of the polyester film wherein the content of the polyester resin component (A) in the resin (P) of the layer X is not less than 20 wt.% and not more than 70 wt.% based on the whole weight of the layer X; the content of the glycidyl group-containing acrylic compound component (B) in the resin (P) of the layer X is not less than 15 wt.% and not more than 60 wt.% based on the whole weight of the layer X; and the ratio of a sulfonate group-containing dicarboxylic acid component in the polyester resin component (A) is not less than 4 mol% and less not more than 30 mol% based on the whole dicarboxylic acid components of the polyester resin component (A).
