PROBLEM TO BE SOLVED: To provide a resin composition for optical solid shaping which has quick curability, and good mechanical properties, weatherability, and after fabricability of an obtained solid shape. SOLUTION: The composition comprises a urethane (meth)acrylate (A) having two or more radically polymerizable (meth)acryloyl groups, one or more amide groups, and two or more urethane groups which is obtained by reacting an amidohydroxy compound having one or more amide groups and two or more hydroxy groups, a diol selected from a polyether diol, a polyester diol, and a polycarbonate diol, an organic diisocyanate compound, and a hydroxy group-containing (meth)acrylate, an ethylenically unsaturated compound (B) having a radically polymerizable functional group other than the component (A), elastomer particles (C) having a core/shell structure in which the core component is one or more kinds selected from an acrylic rubber, a silicone rubber, and a silicone/acrylic composite rubber, and a radical polymerization initiator (D).
