A thermosetting resin composition containing as essential resin components (a) a maleimide compound modified with furfuryl alcohol, (b) an epoxy resin and (c) a polyvinyl formal, and a latent curing agent or a curing accelerator which is at least one compound selected from the group consisting of dicyandiamide, boron trifluoride-amine complexes, metal chelate compounds, and silicone compounds and organo-silane compounds having at least one hydroxyl group bonded directly to silicon atom, is found to be capable of B-staging with good storage stability and provides a heat-resistant resin composition having excellent electric characteristics at high temperatures after curing. The composition can suitably be coated on a glass cloth or a mica tape to give a pre-preg tape which can maintain its flexibility for a long time.
