<p>A prepreg is provided to ensure high flame inhibition without a halogen compound and phosphorus compound and low coefficient of thermal expansion in a planar direction. A resin composition comprises a cyanate ester resin(A) indicated as the following chemical formula(1), non - halogen epoxy resin(B), silicone rubber powder(C) and inorganic filler(D). In the chemical formula 1, R shows a hydrogen atom or methyl radical; n is at least, an integer of 1. The content of the inorganic filler (D) is 50-150 parts by weight based on the total content 100.0 parts by weight of cyanate ester resin(A) and non - halogen epoxy resin(B).</p> |
