FIELD: electrothermy; flat electric heaters. SUBSTANCE: plate-type electric heater (Fig. 1) has textile resistor unit 1 and electrodes 2, 3 disposed between insulating layers 6, 7 of coating. One of insulating layers, such as layer 6, is made of wound segment 10 of convex radial curvature with definite arrangement of textile resistor unit 1. Proposed method for manufacturing plate-type electric heater is characterized in that sheath produced in winding and curing layer 6 of coating is partially cured. EFFECT: enhanced operating reliability and stability of thermal characteristics of heater. 1 cl, 8 dwg
