Abstract

A curable resin composition that has low viscosity and forms a cured product having excellent mechanical physical properties, a cured product, and a three-dimensional object. The curable resin composition contains a urethane resin (A) containing a (meth)acryloyl group, and a monofunctional (meth)acrylate compound (B1) and/or a bifunctional (meth)acrylate compound (B2), in which the urethane resin (A) is formed using, as essential reaction raw materials, a polyester polyol (a1), a polyisocyanate (a2), and a compound (a3) containing a hydroxyl group and a (meth)acryloyl group, and the polyester polyol (a1) is formed using, as essential reaction raw materials, a glycol (a1-1) containing a hydrocarbon group in a side chain, and a polycarboxylic acid (a1-2).
