  The present invention provides a resin composition for optical shaping that emits a weaker odor, enables easy fabrication of an object by virtue of its low viscosity, and can be made into a fabricated product having desirable toughness and water resistance when used for stereolithographic fabrication (particularly by vat stereolithography) and that is particularly suited for dental occlusal splints, mouth guards, and denture base materials. The present invention relates to a resin composition for optical shaping comprising: an α,β-unsaturated double bond group-containing compound (A) having a ring structure (a) containing a nitrogen atom; a (meth)acrylic acid ester compound (B) having a boiling point of 280°C or more at normal pressure, having a carbocyclic group, and having no nitrogen-containing heterocyclic group; a photopolymerization initiator (C); and optionally, a polyfunctional polymerizable monomer (E) having a molecular weight of 500 or less and not comprised in the α,β-unsaturated double bond group-containing compound (A) and the (meth)acrylic acid ester compound (B), wherein the content of the polyfunctional polymerizable monomer (E) having a molecular weight of 500 or less is 20 mass% or less relative to the total amount of polymerizable compounds comprised in the resin composition for optical shaping.
