To provide a resin composition for optical three-dimensional modeling which gives a three-dimensional object that has high impact strength, is less apt to break, has excellent toughness, has not yellowed, has a high light transmission, and is excellent in terms of color tone and transparency. The resin composition for optical three-dimensional modeling comprises a radically polymerizable organic compound (A), a cationically polymerizable organic compound (B), a radical polymerization initiator (C), and a cationic polymerization initiator (D), and a poly(alkylene glycol) mono(meth)acrylate (A-1) as a part of the radically polymerizable organic compound (A), and an oxetane compound (B-1) as a part of the cationically polymerizable organic compound (B).
