PROBLEM TO BE SOLVED: To provide a film which has high hiding performance and reflection characteristics in a specified range of film thicknesses and is useful for a variety of reflecting members having high restriction on a leakage of light. SOLUTION: A laminate polyester film which comprises on at least one side of the polyester-based resin layer including a light-shielding agent, laminating a polyester-based resin layer containing 3-30 wt.% of a white pigment of an average particle size of 0.1-1.0μm, and has a total thickness of the film of 10-19μm, an optical density, OD, of the film of 4.0 or larger, and a spectral reflectance of the surface of a layer A to the light ray of the 460 nm wavelength of 70% or larger.
