Abstract:
1. An epoxy resin composition, comprising an epoxy resin and a curing agent as essential components, wherein the epoxy resin has respective structural units of: a glycidyloxy group-containing aromatic hydrocarbon group (E), an alkoxynaphthalene type structure or alkoxyanthracene type structure group (B), and a divalent hydrocarbon group (X) selected from methylene, an alkylidene group and an aromatic hydrocarbon structure-containing methylene group, and the epoxy resin has, in a molecular structure, a structure in which the glycidyloxy group-containing aromatic hydrocarbon group (E) and the alkoxynaphthalene type structure or alkoxyanthracene type structure group (B) are bonded via the divalent hydrocarbon group (X) selected from methylene, the alkylidene group and the aromatic hydrocarbon structure-containing methylene group, wherein no glycidyloxy group is directly bonded to the alkoxynaphthalene type structure or alkoxyanthracene type structure group (B) wherein the alkoxynaphthalene type structure or alkoxyanthracene type structure group (B) is a structure selected from the group consisted of alkoxynaphthalene type structures represented by the following structural formulas B1 to B15, and an alkoxyanthracene structure represented by the following structural formula B16, wherein
