Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an organic peroxide composition by which the organic peroxide composition having a small particle size can efficiently be produced with good operability. SOLUTION: The organic peroxide composition is produced through the following first to fourth steps. In the first step, an organic peroxide solution is prepared by dissolving the organic peroxide in a first solvent at a temperature of not higher than the 10-hr half-life temperature of the organic peroxide. In the second step, the organic peroxide is crystallized to a fine powder shape by putting the organic peroxide solution in a second solvent having a solubility of the organic peroxide smaller than that of the first solvent while stirring, and filtering the crystallized product to provide a crude filter product. In the third step, the first solvent contained in the crude filter product is substituted with a third solvent having a solubility smaller than that of the solvent and the boiling point of ≥30°C and
