Polyethylene terephthalate or lavsan is used as the heat-resistant fabric base. The invention makes it possible to improve the performance characteristics of a flexible resistive heating element, namely the reliability, efficiency and manufacturability both of the resistive element itself and of flexible electric heaters based thereon.
