Abstract: A resin composition contains: a curable resin (A); an acrylic-monomer copolymer (B) having a structure expressed by formulae (1) to (3) and having a weight average molecular weight equal to or greater than 10,000 and equal to or less than 900,000; an inorganic filler (C) where a molybdenum compound is present on at least a part of a surface thereof; and another inorganic filler (D) different from the inorganic filler (C). R1 is either a hydrogen atom or a methyl group. R2 includes at least one of a glycidyl group or an epoxidized alkyl group which is selected from the group consisting of a hydrogen atom, an alkyl group, the glycidyl group, and the epoxidized alkyl group. R3 is either a hydrogen atom or a methyl group. R4 is Ph (phenyl group), —COOCH2Ph, or —COO(CH2)2Ph.
