To provide an organosol composition that is stabilized even if PTFE particles are contained in large quantities.
A method for preparing an organosol composition of a fluororesin particle (X) insoluble in an organic solvent (S) comprises: step (I) of mixing an aqueous dispersion of the fluororesin particle (X) insoluble in the organic solvent (S) with an aqueous dispersion of a polymer (B) soluble in the organic solvent (S); step (II) of adding an water-soluble organic solvent (D) for coagulation to the resulting aqueous dispersion mixture so as to coagulate the fluororesin particle (X) insoluble in the organic solvent (S) and the polymer (B); step (III) of separating the resulting water-containing coagulated product (E) of the fluororesin particle (X) insoluble in the organic solvent (S) and the polymer (B) from a liquid layer; step (IV) of mixing and stirring the resulting water-containing coagulated product (E) with the organic solvent (S) so as to disperse the water-containing coagulated product (E); and step (V) of removing moisture from the resulting water-containing organic dispersion (F).
