Zusammenfassung:	To provide a prepreg that results in fiber-reinforced plastic with improved toughness while maintaining strength and elastic moduli, and fiber-reinforced plastic formed using the prepreg.SOLUTION: A prepreg contains a matrix resin composition and reinforced fiber. The matrix resin composition contains epoxy resin and (meth)acryl monomers. The ratio R of the double bond equivalent of the (meth)acryl monomers to the epoxy equivalent of the epoxy resin (double bond equivalent/epoxy equivalent) is 1.0 or more.SELECTED DRAWING: None 【課題】強度と弾性率を維持しつつ、靭性が改善された繊維強化プラスチックを得ることができるプリプレグ、及びこのプリプレグを用いて形成された繊維強化プラスチックの提供。【解決手段】マトリクス樹脂組成物と強化繊維とを含むプリプレグであって、前記マトリクス樹脂組成物が、エポキシ樹脂及び（メタ）アクリルモノマーを含み、前記（メタ）アクリルモノマーの二重結合当量と、前記エポキシ樹脂のエポキシ当量との比Ｒ（二重結合当量／エポキシ当量）が１．０以上である、プリプレグ。【選択図】なし
