Claim:
1. A fluorinated elastomer composition comprising the following tetrafluoroethylene/propylene copolymer (a), the following 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, tetrafluoroethylene/propylene copolymer (a): a copolymer comprising from 45 to 70 mol % of units derived from tetrafluoroethylene, from 30 to 55 mol % of units derived from propylene, and from 0 to 20 mol % of units derived from other monomer, and ethylene/tetrafluoroethylene copolymer (b): a copolymer comprising from 45 to 70 mol % of units derived from tetrafluoroethylene, from 30 to 55 mol % of units derived from ethylene, and from 0 to 20 mol % of units derived from other monomer.
