PROBLEM TO BE SOLVED: To obtain a new fluorine-containing amide compound having a low surface energy, capable of giving an elastomer excellent in solvent resistance, chemical resistance, releasability and water repellency, and useful for a crosslinking agent for a curing silicone rubber composition, or the like. SOLUTION: This compound is expressed by formula I [Rf is a bivalent perfluroalkylene or a bivalent perfluoropolyether; R1-R4 are each H or a (substituted) monovalent hydrocarbon] and is e.g. a compound of formula II. The compound of formula I is obtained e.g. by reacting a compound having oxyfluoride groups in its both ends and expressed by the formula FCO-Rf-COF with a silylated aniline expressed by formula III in the presence of a catalyst such as triethylamine or the like.
