PROBLEM TO BE SOLVED: To provide a white laminated polyester film excellent in concealability and whiteness, hard to generate the lowering of whiteness even if exposed to ultraviolet rays or high temperature and high humidity environment for a long time, having yellowing resistance, that is, good weatherability and suitable for use as a data recording/printing material. SOLUTION: The white laminated polyester film has whiteness (b0) and a yellowing degree (Δb) satisfying formula, -6.0<=b0<=-2.0 (1) and formula,Δb<=3.5 (2).
