The present invention relates to a new multi-component oxidation catalyst that can be effectively used in, for example, epoxidation reaction of olefins, etc., is inexpensive, versatile, and has high catalytic activity, and the catalyst is used as a catalyst. It aims at providing the manufacturing method of the epoxy body by the hydrogen peroxide oxidation of an olefin. The present invention relates to a multi-component oxidation catalyst comprising a tungsten compound, a quaternary ammonium salt, phosphoric acids and / or boric acids, and a hydrogen sulfate. The present invention also relates to a method for producing an epoxy compound, characterized in that an olefin is oxidized with hydrogen peroxide in the presence of the multicomponent oxidation catalyst. The epoxy compound obtained by the production method of the present invention is useful as an intermediate for agricultural chemicals or medicines, as a raw material for various polymers, and the like.
