Abstract
An epoxy resin composition includes: (A) an epoxy resin containing a compound represented by the following Formula (I); (B) a phenol resin containing a compound represented by the following Formula (II); and (C) a dihydroxynaphthalene compound containing a compound represented by the following Formula (III). In Formula (I), R represents a hydrogen atom, and n represents an integer from 0 to 10. In Formula (II), R1 represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or an alkoxy group having 1 or 2 carbon atoms, and each R1 may be the same as or different from another R1. n represents an integer from 0 to 10. In Formula (III), R1 represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or an alkoxy group having 1 or 2 carbon atoms.
