Abstract
Provided is a composition comprising a perfluoroelastomer and a filler, wherein the filler contains silicon carbide and graphite, and a ratio (area (C)/area (SiC)) of an area (C) of a peak derived from the graphite in the filler to an area (SiC) of a peak derived from the silicon carbide in the filler is 0.7 or more.
