PROBLEM TO BE SOLVED: To provide an organosol composition that is stabilized even if PTFE particles are contained in large quantities.SOLUTION: The organosol composition of PTFE particles is an organosol that contains PTFE particles (A), a polymer (B), and an organic solvent (S). (1) The polymer (B) is soluble in the organic solvent (S). (2) The content of PTFE particles (A) is at least 50 mass% of the total amount of PTFE particles (A) and the polymer (B). (3) In the state where the total solid component concentration of the PTFE particles (A) and the polymer (B) is 5 mass%, the sedimentation rate of the PTFE particles after 48 hours is ≤60%.
