PROBLEM TO BE SOLVED: To provide a white laminated polyester film which shows excellent bluish whiteness and smoothness. SOLUTION: This white laminated polyester film is composed of at least, two layers of a white polyester layer (A) and a white polyester layer (B), and has at least one projecting inflexion between 350-500 nm in curve of degree of total ray reflectivity, in the range of 350-700 nm measured from the white polyester layer (A) side, a peak reflectivity at the position of the inflexion point, is larger than the average reflectivity at least by 5% in the range of 500-700 nm.
