EPOXY RESIN COMPOSITION, PREPREG, METAL CLAD LAMINATE, AND MULTILAYER PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition which is excellent in drillability, moldability, and interlayer adhesion, and in which a desmear treatment can be preferably performed.

SOLUTION: The epoxy resin composition includes an epoxy resin, a hardener, and an inorganic filler. The epoxy resin is an epoxy resin having a dicyclopentadiene skeleton, and an epoxy resin having a novolac skeleton. The hardener is a phenol resin hardener having a biphenyl skeleton. The inorganic filler is spherical silica surface-treated with an epoxysilane, and aluminum hydroxide. The content of the spherical silica for the whole amount of the epoxy resin composition is 20 to 50 mass%. The content of the aluminum hydroxide for the whole amount of the spherical silica is 2 to 15 mass%.
