<P>PROBLEM TO BE SOLVED: To provide an epoxy resin composition which, even when used under high-temperature environment, achieves little decrease in elastic modulus and mass when made into a cured product. <P>SOLUTION: The epoxy resin composition contains (A) an epoxy resin, (B) a phenol resin, and (C) an antioxidant, wherein (B) the phenol resin contains a phenol resin obtained by the reaction of a dihydroxybenzene derivative and an aldehyde compound. Preferably, (B) the phenol resin contains a compound represented by general formula (I). In formula (I), R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are each a hydrogen atom, a substituted or unsubstituted 1-18C hydrocarbon group, or a substituted or unsubstituted 1-18C hydrocarbonoxy group, and a plurality of R<SP POS="POST">1</SP>s and R<SP POS="POST">2</SP>s may be the same or different from each other; R<SP POS="POST">3</SP>is a hydrogen atom or a substituted or unsubstituted 1-18C hydrocarbon group, and a plurality of R<SP POS="POST">3</SP>s may be the same or different from each other; n is an integer of 0-20; and ms are each independently an integer of 0 or 1, wherein the sum of n and m is 1 or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
