PROBLEM TO BE SOLVED: To provide an organic peroxide composition having a good stability and giving a resin composition having an excellent stock stability when blended in a resin as a curing agent, to provide a cured-resin preparation process enabling a fast curing of a resin by using an organic peroxide composition as a curing agent and a metallic soap as a curing promoter and to provide a cured material prepared by this method. SOLUTION: This organic peroxide composition contains an organic peroxide and a disulfide compound of general formula (1). A cured material of a thermosetting resin is prepared by curing the thermosetting resin using this organic peroxide composition as a curing agent and a metallic soap as a curing promoter. (wherein X is at least one selected from the group consisting of atoms and substituted groups which have high electron-withdrawing property than hydrogen).
