    摘要: Disclosed is a polyurethane-modified epoxy resin composition capable of satisfying both high toughness and high elasticity. This epoxy resin composition is an epoxy resin composition, in which (A) a polyurethane-modified epoxy resin having a polycarbonate structure in the molecule and having a urethane modification rate of 20 to 60% by weight, (B) a non-polyurethane-modified epoxy resin that is liquid at 30°C, (C) a solid epoxy resin having a glass transition temperature or melting point of 50°C or higher and (D) an amine-based curing agent that is dicyandiamide or a derivative thereof are as essential components, and 20.0 to 50.0% by weight of (A), 0.1 to 50.0% by weight of (B) and 0.1 to 50.0% by weight of (C) are contained relative to the total of (A) to (D).
