Abstract

A resin composition used to prepare a sheet-like prepreg by impregnating a substrate with the resin composition includes an epoxy resin that contains a naphthalene-modified epoxy resin, and a triazine-modified novolac resin. A sheet-like prepreg is formed by impregnating a substrate with the resin composition. A laminate formed using the prepreg exhibits excellent flame retardancy, solder heat resistance, and lead-free heat resistance, has a small coefficient of linear expansion in the thickness direction, and has excellent adhesion to a conductor circuit.
