To provide a resin composition capable of producing a heat-dissipating insulating cured product having high heat dissipation, high insulation, and low elasticity. A resin composition comprising a hydrogenated styrene butadiene rubber and a derivative component thereof, (B) an epoxy resin component, and (C) a filler component, the components (A) and (B). (A) component is 40-90 mass% with respect to the total amount of (B), and (B) component is 10-60 mass%, and said (C) with respect to 100 mass parts of total amount of (A) component and (B) component ) Component is 150 to 500 parts by mass, and the shape of 90% by mass or more of the component (C) is spherical.
