A novel alicyclic epoxy resin having no ester bond in each molecule, and a precursor of the alicyclic epoxy resin. The precursor is a diolefin compound represented by formula (1) (wherein each of the plurality of R's independently represents a hydrogen atom or an alkyl group having 1-6 carbon atoms), and the epoxy resin is obtained by epoxidizing the diolefin compound. |
