[Problem] The purpose of the invention, in view of the above circumstances, is to provide a silicone-modified epoxy resin composition giving a cured article having low gas permeability and excellent strength and an epoxy resin cured article obtained by curing this composition. [Solution] Epoxy resin represented by formula (1). (In the formula, R1 represents an alkylene group having 2-6 carbon atoms optionally containing an ether bond, R2 represents a monovalent aliphatic hydrocarbon group having 1-6 carbon atoms or a monovalent aromatic hydrocarbon group having 6-12 carbon atoms, R3 represents an oxygen atom or phenylene group, k represents 1-10 by average value, m represents an integer of 0-2, and n represents 0-10 by average value. Multiple R1-R3, k, and m present in the formula may each be the same or different.) |
