PURPOSE: To obtain the subject fiber useful for a lining on the inner wall of a combustion chamber, for a filter for removing fine particles from the exhaust gas of a Diesel engine, etc., by forming the coating film of a nitrogen-containing compound on the surface of a ceramic fiber, etc. CONSTITUTION: A ceramic fiber, glass fiber or metal fiber is used as a base material, and the antioxidizing coating film 3 of a oxynitride glass is formed on the surface of the base material. The content of the nitrogen in the coating film components is adjusted to reduce the difference between the thermal expansion coefficients of the base material and the coating film, preferably into a value of <=8×10<-6> / deg.C. The conjugate fiber is excellent in oxidation resistance against high temperature combustion gases and exhaust gases.
