Abstract

Provided is an epoxy-amine adduct that offers high reactivity, contributes to better adhesion between a resin and a reinforcing fiber in a fiber-reinforced composite material, and can be easily blended with another component such as a resin. The epoxy-amine adduct has two or more amino groups per molecule and is obtained by a reaction of an epoxy compound (A) having two or more alicyclic epoxy groups per molecule with an amine compound (B) having two or more amino groups per molecule. The epoxy compound (A) is preferably a compound represented by Formula (a):
