The present invention provides a cyanate ester-based resin composition capable of imparting good dielectric properties in a high frequency region to a printed wiring board while sufficiently ensuring compatibility of resin components. A resin composition according to the present invention comprises (A) a saturated thermoplastic elastomer having a styrene skeleton, (B) a cyanate ester compound, (C) a monofunctional phenol, and (D) an epoxy resin. And the mass ratio of styrene to the mass of the entire component (A) is 10% to 70%. [Selection figure] None |
