Provided is a compression molding composition, in which an emulsion-polymerized polytetrafluoroethylene (PTFE) and a filler are mixed in a substantially uniform manner without generating an aggregate, and the used PTFE is not particularly limited. The compression molding composition includes emulsion-polymerized polytetrafluoroethylene, a heat-processible fluoropolymer, and a filler, the melt flow rate (MFR) of the heat-processible fluoropolymer is from 0.01 to 100 g/10 min, and the content of the heat-processible fluoropolymer is from 1 to 40 mass % relative to the total of the emulsion-polymerized polytetrafluoroethylene and the heat-processible fluoropolymer.
