PROBLEM TO BE SOLVED: To provide a polyol crosslinkable fluororubber composition which simultaneously enables improvement of the storage stability of stock, prevention of the adhesion of stock on kneading, short-time vulcanization, improvement of mold release characteristics on vulcanization molding, prevention of staining by metallic ions, lowering of the adhesion of a crosslinked product due to the improvement of crosslink density and the like without substantially damaging original state properties, compression set-resistant properties, and furthermore various favorable properties inherent in fluororubbers. SOLUTION: The polyol crosslinkable fluororubber composition comprises 100 pts. wt. polyol crosslinkable fluororubber, 0.5-10 pts. wt. perfluoroalkane represented by the formula: F(CF<SB>2</SB>)<SB>2n</SB>F (wherein n is an integer of 5-30), 1H-perfluoroalkane represented by the formula: F(CF<SB>2</SB>)<SB>m</SB>H (wherein m is an integer of 10-30) or a mixture thereof, and 0.5-2 pts. wt. basic magnesium-aluminum-hydroxycarbonate hydrate.
