1. A resin composition for stereolithography comprising a polymerizable monomer (a), a photopolymerization initiator (b), an inorganic particle (c) having an average particle diameter of 5 to 500 nm, and a hindered phenolic compound (d), wherein
the content of the photopolymerization initiator (b) is 0.1 to 10 parts by mass relative to 100 parts by mass of the polymerizable monomer (a),
the content of the inorganic particle (c) is 50 to 400 parts by mass relative to 100 parts by mass of the polymerizable monomer (a), and
the content of the hindered phenolic compound (d) is 5.0 to 500 parts by mass relative to 100 parts by mass of the photopolymerization initiator (b).
