The present invention provides a resin composition with which a laminate, a printed wiring board, and the like that not only have high thermal conductivity but have good moldability with the occurrence of cracks and voids suppressed can be implemented simply and with good reproducibility, and a prepreg, a laminate, a metal foil-clad laminate, and the like using the same. The resin composition of the present invention is a resin composition comprising at least a cyanate ester compound (A), an epoxy resin (B), a first inorganic filler (C), and a second filler (D), wherein an average particle diameter ratio of the first inorganic filler (C) to the second inorganic filler (D) is in the range of 1:0.02 to 1:0.2.
