Abstract
A cyanate ester resin composition contains: a cyanate ester resin; a curing agent or a curing accelerator; silica microparticles; and core-shell rubber particles; in which the resin composition includes from 1 to 5 parts by mass of the silica microparticles and from 2 to 10 parts by mass of the core-shell rubber particles based on 100 parts by mass of the cyanate ester resin, and a mass ratio of the silica microparticles to the core-shell rubber particles is from 1/1 to 1/5.
