Abstract

See full text

A curable resin composition of the present invention contains 1 to 100 parts by mass of a polymer fine particle (B) relative to 100 parts by mass of an epoxy resin (A), wherein the polymer fine particle has a core-shell structure, the core layer of the polymer fine particle is diene rubber, the content of the epoxy group of the polymer fine particle (B) is 0.01 to 0.2 mmol/g. A curable resin composition (I) of the first embodiment contains 0.5 to 30 parts by mass of fumed silica as an inorganic filler (C). In addition, a curable resin composition (II) of the second embodiment contains bisphenol A epoxy resin and rubber-modified epoxy resin and/or urethane-modified epoxy resin as the epoxy resin (A).
