PROBLEM TO BE SOLVED: To provide a non-cellophane-based film which has excellent antistaticity, good hand tearing easiness, and excellent adhesiveness to inks and adhesives. SOLUTION: This biaxially oriented laminated polyester film is characterized by having a surface specific resistance of≤5×10<SP>12</SP>Ω/ square on at least one side and having tensile breaking strengths of 40 to 200 MPa in the longitudinal and latitudinal directions, respectively. The biaxially oriented laminated polyester film preferably has a layer (A layer) comprising a polyester raw material comprising at least one of a copolymerized polyethylene terephthalate and a copolymerized polybutylene terephthalate and a layer (B layer) comprising a polyester raw material, wherein the melting point of the B layer is preferably larger by≥10°C than the melting point of the A layer.
