Abstract
There is provided an epoxy resin composition comprising a (meth)acrylic copolymer (A), an epoxy resin (B), and a curing agent (C), wherein the (meth)acrylic copolymer (A) has a constituent unit derived from a macromonomer (a) and a constituent unit derived from a vinyl monomer (b), and wherein a glass transition temperature (TgB) of a polymer obtained by polymerizing only the vinyl monomer (b) is 25° C. or less.
