Abstract: A prepreg containing: a resin composition; and a woven fabric base material. The resin composition contains: (A) at least one of an epoxy resin having a naphthalene skeleton and a phenolic curing agent having a naphthalene skeleton; (B) a high molecular weight compound having at least structures represented by formulae (1) and (2 ) or at least a structure represented by the formula (2), no unsaturated bond between carbon atoms, and a weight-average molecular weight of 250,000 to 850,000; and (C) an inorganic filler. (C) The inorganic filler is subjected to surface treatment with a silane coupling agent represented by a formula (3).
