FIELD: heating means used in industry and at home. SUBSTANCE: proposed ceramic electric heating element includes backing made of aluminum nitride and heating conductor with impurities. Heating conductor, termination and mounting pads are produced from refractory metal of wolfram and/or molybdenum and/or nickel type with additives of same material as backing has. Process of manufacture of ceramic electric heating element consists in deposition and firing in of heating conductor into backing. Heating conductor, termination and mounting pads are fired in backing jointly and simultaneously with its baking in protective gas atmosphere of nitrogen mixed with hydrogen or without the latter at temperature of 1700-1900 C. EFFECT: efficiency of heating, compactness and high functional reliability of ceramic electric heating element and versatility of its usage. 61 cl, 31 dwg
