(57) [Problem] To obtain an epoxy resin having low viscosity but low crystallinity, and to use the same in an epoxy resin composition to reduce the viscosity of the epoxy resin composition, to reduce the solvent, and to eliminate the solvent. In addition, the cured product achieves low moisture absorption. SOLUTION: Formula (1) (Wherein, a plurality of Rs are each independently a hydrogen atom, It represents an alkyl group, an aryl group or an allyl group having 1 to 10 carbon atoms, and 25 to 100% of the whole is an allyl group. i Is a real number of 2-3, and j is a real number of 3-4) to produce an epoxy resin obtained by glycidylation of a compound represented by the formula: This is used as a constituent material of the epoxy resin composition. |
