PROBLEM TO BE SOLVED: To provide a laminated polyester film for optical resin solution film-making which is excellent in mold-release properties of an optical resin film, luminescent spot fault, and transparency. SOLUTION: In the laminated polyester film for optical resin solution film-making, a laminated film comprising a composition (A) and an acrylic resin (B) having a 12-25C alkyl chain is formed on at least one side of a polyester film. The composition (A) is a composition comprising polythiophene and a polyanion and/or a composition comprising a polythiophene derivative and a polyanion, and the number of internal foreign matter of at least 100μm contained in the laminated polyester film is below 10/m<SP>2</SP>.
