PROBLEM TO BE SOLVED: To provide a curable fluoropolyether rubber composition which gives a cured material excellent in acid resistance and alkali resistance as well as in heat resistance, chemical resistance, solvent resistance, a mold release property, water repellency, oil repellency, weathering and the like, can be used in a wide range of applications, and is useful for e.g. a sealing material for a semiconductor, an O-ring, a diaphragm and a sealing material for an automobile or an airplane, a roll material for a copying machine, and a constituent material for electrodes of a secondary battery and a fuel cell. SOLUTION: The rubber composition contains (A) a linear fluoropolyether compound having at least two alkenyl groups in the molecule, with a perfluoropolyether structure in the main chain, (B) an organosilicon compound having at least two hydrogen atoms bound to a silicon atom in the molecule, with all of the silicon atoms bound to a hydrogen atom being combined with a benzene ring, and (C) a hydrosilylation catalyst.
