PROBLEM TO BE SOLVED: To provide a method for efficiently and economically carrying out epoxidation of an alicyclic olefin compound by using a solvent having low toxicity. SOLUTION: This method for epoxy compound production is characterized in that an alicyclic olefin compound represented by general formula (II) (X is an oxygen atom, a sulfur atom, a functional group of SO, SO2 , CH2 , C(CH3 )2 , CBr2 , C(CBr3 )2 , C(CF3 )2 , C(CCl3 )2 or CH(C6 H5 ) or a mere single bond connecting two alicycles; R to R may be the same or different and are each a hydrogen atom, a halogen atom, an oxygen atom or a hydrocarbon group which may contain a halogen atom or an alkoxy group which may contain a substituent group) is epoxidized by using an aliphatic percarboxylic acid not substantially containing water to give an alicyclic epoxy compound represented by general formula (I).
