PROBLEM TO BE SOLVED: To provide a silicone resin excellent in fracture toughness. SOLUTION: A rubber-modified rigid silicone resin includes a copolymerized reaction product of an organosilicon composition (A) selected from the group consisting of an organosilicon resin (I), a hydrolysable precursor (II) of formula (I), and a hydrolyzate (III) of (II) and a silicone rubber (B), wherein the organosilicon composition (A) and the silicone rubber (B) exist by such relative amounts that the rubber-modified rigid silicone resin has a Young's modulus of at least 6.9×10<SP>8</SP>Pa.
