The purpose of this invention is to provide an epoxy resin composition with which it is possible to form a cured epoxy resin having excellent initial transparency and weather resistance as well as excellent adhesion to various substrates. This invention pertains to an epoxy resin composition containing (A) an epoxy resin, (B) a polycarboxylic anhydride including a structural unit represented by general formula (1), and (C) a specific phosphonium compound. (In the formula, A represents a cycloalkylene group or the like, R 1 -R 10 are the same or different and each represent a hydrogen atom or an optionally substituted C1-10 alkyl group, and two of the R 1 -R 10 groups may bond together to form a divalent group.) |
