Epoxy resin compositions which comprise an epoxy resin (A), an active ester compound (B), and a triazine-containing cresol novolac resin (C), when cured and roughened, exhibit a roughed surface which has a high adhesion strength to a metal plated conductor, even though the roughness of the roughed surface is small, and provide an insulating layer which has a low coefficient of linear expansion and a low dielectric loss tangent.
