    摘要: A fluorine rubber composition contains a component A that is a base rubber containing a hydrogen-containing fluorine rubber as a main component, a component B that is a compound having a perfluoropolyether skeleton, and a component C that is a powdery filler having a bulk density of 0.4 g/cm3 or less. A part or whole of the component B contains an alkenyl group in a molecule. (pC/dC)/(pB/dB)≥4 is satisfied wherein dB is a density of the component B, pB is a content of the component B relative to 100 parts by mass of the component A, dC is the bulk density of the component C, and pC is a content of the component C relative to 100 parts by mass of the component A.
