Abstract: PROBLEM TO BE SOLVED: To provide a laminated polyester film excellent in the property of adhesion to a coating material, a flame-retardant polyester film using it, a copper-clad laminate, and a circuit board. SOLUTION: In the laminated polyester film, a resin layer containing a polyester resin and an oxazoline-based cross-linking agent is laminated on at least one side of a polyester film, 40 mol% or more of all diol components constituting the polyester resin is diethylene glycol, and the mass ratio between the polyester resin and the oxazoline-based cross-linking agent, constituting the resin layer, is in the range of 20/80-80/20. In the flame-retardant polyester film, a layer containing a polyimide is laminated on both the sides of the laminated polyester film. The copper-clad laminate uses the flame-retardant polyester film.
