PROBLEM TO BE SOLVED: To provide a fluororubber composition not impairing flowability and molding processability even if a large amount of magnetic powder is mixed. SOLUTION: The fluororubber composition comprises, in a composition composed of magnetic powder (A) and a fluororubber (B) having a Mooney viscosity of 20-50 ML(1+10) at 100°C, 5-95 pts.wt. of the component (A) based on 100 pts.wt. of the total of the components (A) and (B). The component (A) is preferably (A-1): BaM<SB>X</SB>Fe<SB>(12-X)</SB>O<SB>19</SB>, (A-2): Ba<SB>3</SB>M<SB>2</SB>Fe<SB>24</SB>O<SB>41</SB>or (A-3): Ba<SB>2</SB>M<SB>2</SB>Fe<SB>12</SB>O<SB>22</SB>(wherein M is one or more kinds of metal elements selected from the metal element group of Ti, Co, Ni, Zn and Mn; and x is an integer of≥1 and≤11).
