Abstract
It is intended to provide a resin composition that suppresses the thermal expansion of a printed circuit board more than ever and also prevents the bleedout of substances from the printed circuit board, while maintaining a high glass transition temperature. The resin composition of the present invention contains an alkenyl-substituted nadimide, a maleimide compound, and an epoxy-modified cyclic silicone compound.
