Disclosed is a perfluoroelastomer composition comprising 100 parts by weight of a perfluoroelastomer containing a cyano group as a crosslinkable group, 0.2 to 5 parts by weight of a bisamidoxime compound vulcanizing agent represented by the general formula: HON═C(NH2)—(CF2)n—C(NH2)═NOH (n: an integer of 1 to 10), and 0.005 to 0.3 parts by weight of a coloring agent with a melting point of 300° C. or above. This perfluoroelastomer composition provides a colored molded product that does not form blooms under high temperature conditions of 300° C. or above, and that can be effectively used, for example, as a sealing material for semiconductor manufacturing devices.
