The purpose of the present invention is to provide a curable composition having exceptional storage stability, the curable composition being easily cured by moisture or low-temperature heating and having high shear strength after curing. The present invention is a curable resin composition that contains a urethane prepolymer having isocyanate groups, a coated amine formed by using a filler to coat solid amine having a melting point of 50 degrees or higher, an isocyanate group-containing compound having an isocyanate group bonded to an aliphatic hydrocarbon group and further having a hydrolyzable silyl group or (meth)acryloyl group, and a tertiary amine compound.
