摘要：
The prepreg comprises: a reinforcing fiber layer including reinforcing fibers and a resin composition with which the space between fibers of the reinforcing fibers is impregnated and which contains (A) a benzoxazine resin, (B) an epoxy resin, and (C) a curing agent having 2 or more phenolic hydroxy groups in a molecule; and a surface layer provided on a surface of the reinforcing fiber layer and containing the (A) to (C) components, and (D) polyamide resin particles having an average particle size of 5 to 50 µm, wherein the polyamide resin particles include a polyamide 12 resin particle and a polyamide resin particle made of a copolymer in which caprolactam and laurolactam are copolymerized at a molar ratio of 9:1 to 7:3.
