Provided are a resin composition that can realize a prepreg, a metal foil-clad laminate and the like high in light reflectance in an ultraviolet region and in a visible light region, small in the reduction in light reflectance due to a heating treatment and a light irradiation treatment, good in peel strength of metal foil, also excellent in heat resistance after moisture absorption, also good in outer appearance, and also excellent in preservation stability, and a prepreg, a metal foil-clad laminate and the like using the same. The resin composition of the present invention contains at least an epoxy-modified silicone compound (A), a branched imide resin (B) having an isocyanurate group and a carboxyl group, a phosphorus curing accelerator (C), titanium dioxide (D) and a dispersant (E). The branched imide resin (B) is preferably at least one selected from the group consisting of an epoxy-modified branched imide resin, an alcohol-modified branched imide resin and an amine-modified branched imide resin.
