ABSTRACT:
The present invention is a flame-retardant polyester film including resin layers laminated on both surfaces of a polyester film, wherein the resin layer satisfies 15≦(Wc1−Wc2)/Wc0×100≦99 (where Wc0represents the weight of the resin layer, Wc1represents the weight of the resin layer after the temperature thereof is raised from 25° C. to 600° C. in air, and Wc2represents the weight of the resin layer after the temperature thereof is raised from 25° C. to 800° C. in air), and has a non-flammable gas generating rate of 3 to 40 percent over the range of 180° C. to 450° C. The present invention provides a flame-retardant polyester film having an excellent flame retardancy, and adhesive tapes, flexible printed circuits, a membrane switch, a film heater, and a flat cable, each including the flame-retardant polyester film.
