PROBLEM TO BE SOLVED: To provide a resin composition which substantially avoids deterioration of drillability due to higher filling of an inorganic filler and ensures low thermal expandability, high heat resistance and high flame retardancy, a prepreg using the same, and a laminate. SOLUTION: The resin composition contains a thermosetting resin, an inorganic filler and tetrafluoroethylene resin powder, wherein the content of the inorganic filler is 30-70 vol.% based on the total amount of the resin composition, and the content of the tetrafluoroethylene resin powder is 1-10 parts by mass based on 100 parts by mass of the thermosetting resin. The prepreg uses the resin composition. The laminate is formed by laminate molding using the prepreg. COPYRIGHT: (C)2009,JPO&INPIT
