    Abstract: To provide a fluorinated elastomer composition which is excellent in flexibility and oil resistance to lubricant oil such as automatic transmission oil, is less susceptible to heat discoloration and is excellent also in moldability, and a molded product, cross-linked product and covered electric wire, using such a fluorinated elastomer composition. A fluorinated elastomer composition comprising a tetrafluoroethylene/propylene copolymer (a), an ethylene/tetrafluoroethylene copolymer (b) and an ethylene copolymer (c) containing epoxy groups, wherein the mass ratio [(a)/(b)] of the tetrafluoroethylene/propylene copolymer (a) to the ethylene/tetrafluoroethylene copolymer (b) is from 70/30 to 40/60, and the mass ratio [(b)/(c)] of the ethylene/tetrafluoroethylene copolymer (b) to the ethylene copolymer (c) containing epoxy groups is from 100/0.1 to 100/10.
