A multilayer polyester film is characterized in that a polyester (B) layer mainly composed of a polyester (B) is arranged on at least one side of a polyester (A) layer mainly composed of a polyester (A). The multilayer polyester film is also characterized by having an elastic modulus of 20 to 1000 MPa in an atmosphere at 23° C. and an elastic modulus of 10 to 200 MPa in an atmosphere at 120° C., and having substantially no-orientation.
