A resin composition having excellent heat resistance, flame retardance, and moldability, and capable of particularly providing a resin cured product with a low coefficient of thermal expansion is provided. A resin composition according to the present invention contains a cyanate ester compound (A), a maleimide compound (B), an epoxy resin (C), a silicone rubber powder (D), and an inorganic filler (E). The cyanate ester compound (A) contains a compound represented by the following formula (I). The silicone rubber powder (D) is contained in an amount of 40 to 150 parts by mass based on 100 parts by mass in total of the cyanate ester compound (A), the maleimide compound (B), and the epoxy resin (C). The inorganic filler (E) is contained in an amount of 100 to 340 parts by mass based on 100 parts by mass in total of the cyanate ester compound (A), the maleimide compound (B), and the epoxy resin (C). A total content of the silicone rubber powder (D) and the inorganic filler (E) is 140 to 380 parts by mass based on 100 parts by mass in total of the cyanate ester compound (A), the maleimide compound (B), and the epoxy resin (C).
