Abstract: The present invention provide a laminated polyester film which is capable of ensuring a good dimensional stability without being subjected to such a surface saponification treatment with an alkali solution as required for triacetyl cellulose films, is available at low costs, exhibits a good adhesion property to adhesives and a high total light transmittance, and can be suitably used as a protective film for polarizing films. The laminated polyester film of the present invention comprises a polyester film; a coating layer formed on one surface of the polyester film which comprises an acrylic resin or a urethane resin as a main component; and a coating layer formed on the other surface of the polyester film which comprises a urethane resin having a polycarbonate structure. In the preferred embodiment of the present invention, the coating layer comprising the acrylic resin or the urethane resin as a main component has a thickness of 0.04 to 0.15 µm, and the polyester film comprises an ultraviolet absorber.
